Skeptical Eye: News from NCAS July 2026

CSICon 2026

May 1st of this year marked the 50th anniversary of the modern skeptical movement, born near Buffalo, New York, on the second day of the American Humanist Association’s 35th annual conference.  The theme for that day’s talks was, “The New Irrationalisms: Antiscience and Pseudoscience.”  (Read more about this in James Alcock’s Skeptical Inquirer article, “Fifty Years of the Modern Skeptical Movement.”)

To commemorate this auspicious milestone, the Committee for Skeptical Inquiry held its annual conference (CSICon) in Buffalo this June.  For those who were unable to attend, there are brief video recordings already available.  (Based on previous CSICons’ talks eventually showing up online, there may be more to come later.)  For example, on Friday morning, Kenny Biddle strolled through the venue, including the auditorium where Stuart Vyse was presenting “Welcome to the Burned-Over District!”  Susan Gerbic’s snippet of Thursday morning’s “CFI History & Mystery Tour” features Kenny, and she also posted video of Sunday morning’s CSICon Singers with Anthony Trecek-King.

In lieu of more videos becoming available, NCAS presents the following descriptions and commentary from several of its members who attended CSICon 2026.  (Please note that the opinions expressed in this article are the authors’ own and do not necessarily reflect the view of the National Capital Area Skeptics organization.)

Rorschach Theatre: American Apparitions

Rorschach Theatre is a spunky, local theater company whose works for 25 years have often featured themes that are spooky and fantastical. They have mounted stage productions ranging from Toxic Avenger: The Musical to a delightful twist on Beauty & the Beast. Naturally, I’m a fan.

During the COVID lockdown, they conceived a brilliant idea to stay alive: Psychogeographies. If you can’t go to the theater, well, let the theater take you on adventures around town. Each month, subscribers receive a package and a map that lets them go to a location -- at a time of their choosing -- where examining the rest of the package unfolds a bit of a multi-chapter story.  After a few months, a whole new world has been opened. It was such a success that they have continued with new stories and are now in the 6th season. Grace and I have been on board for them all.

Two seasons ago, the story involved cryptids and a possible abduction. They even wove the National Capital Area Skeptics into the storyline! Other seasons involved time travel and even warping between worlds in a multiverse.

We just completed the first chapter of this season called American Apparitions. It is all about ghost hunting around DC. Our initial package included an investigator’s handbook from the “Red Room Society,” complete with suggestions for free ghost hunting apps to download. The map took us to the MLK Jr Library, Chinatown, and even down an alley behind Ford’s Theatre where we tried to record ghostly images and voices. It was a hoot!

It struck us that other skeptics might enjoy this as much as we do. Although chapters 2 and 3 are about to be released, it’s actually easy to join in late since the whole thing is done on your own schedule. They even provide online videos for those who want to “remote view” rather than venture out in person.

Saturday afternoon, July 11, is a special live Ghost Party event. It’s billed as a fundraiser for the company, with drinks, a paranormal scavenger hunt, and dessert. It is a stand-alone event, but thematically tied to American Apparitions. Subscribers get a free ticket. Grace and I share one subscription and just bought a single guest ticket with a subscriber discount for the party.

We would love to meet up with NCAS members for the party or any of the monthly adventures. I hope you will join us.

2026 Candidates for Election

ROB EVON

Rob Evon is an NCAS Life Member and a lifelong supporter of national skeptical and science organizations, including the Center for Inquiry and the Skeptics Society. He has been a frequent attendee of CFI’s CSICon and The Amazing Meeting (TAM), as well as a direct supporter of CFI initiatives such as Teacher Institute for Evolutionary Science (TIES).

He currently serves as Treasurer and a member of the Board of Directors, and previously as Vice President, of one of the nation’s largest branch-level Friends of the Library nonprofit organizations. He brings more than 30 years of senior leadership experience in strategic planning, business development, and governance across both the corporate and nonprofit sectors. His strong commitment to evidence-based analysis, public education, and organizational strategy would help advance NCAS’s mission of promoting critical thinking and scientific understanding.

BRIAN GREGORY

I’m a senior software engineer, currently working for NVIDIA on their supercomputer scheduling software.  A while back, I ran a skeptical video-chat discussion group called “Virtual Drinking Skeptically,” used to host a weekly podcast called “The Virtual Skeptics,” and have somehow managed to (with a lot of help) organize three SkeptiCamp DC (https://skepticampdc.org) events, and continue to work toward organizing the Baltimore Skeptics.


MARY PASTEL

I have been a member of NCAS for over twenty years. I am interested in many pertinent topics but especially in why people choose to believe things that are demonstrably not true. My background is in science and engineering. I have been a researcher, lab director, regulator. By the time I retired I headed up the radiological health part of FDA.


MELISSA POLLAK

Melissa Pollak retired from the National Science Foundation in 2010 after spending nearly three decades at the agency.  During her tenure at NSF, she was responsible for seven chapters of the National Science Board biennial report Science & Engineering Indicators, including the 2000, 2002, 2004, and 2006 chapters on public attitudes toward and understanding of science.  When she began that assignment, she discovered how little attention the science community was giving the public’s belief in pseudoscience.  She was astounded by her colleagues’ unfamiliarity with the problem and lack of concern.  As a result, she made it a goal to give the subject as much coverage as possible in Indicators, as well as in NSF’s increasingly dwindling survey work on public understanding of science.  In October 2005, Ms. Pollak went on a Long Term Professional Development detail at the American Association for the Advancement of Science (AAAS).  After returning to NSF, she was involuntarily re-assigned different duties.  So, to stay involved, she decided to do whatever she could to see that NSF continued to have a role in the work of skeptical organizations.  To that end, NCAS was able to hold some of its monthly public lectures at NSF.  However, with the agency's move to Alexandria in 2017, that arrangement ended.  From 2010 to 2015, Ms. Pollak served as a volunteer at the Science and Entertainment Exchange, a program of the National Academy of Sciences whose main mission is to connect scientists with producers of movies and TV shows to ensure that the science seen on both the small and big screen is as accurate as possible.  She holds a B.S. degree in political science and economics from American University and an M.A. in economics from George Washington University.  Incidentally, it’s now been more than two decades since NSF last undertook any survey work on the public’s belief in pseudoscience.

 

WALTER ROWE

Dr. Walter Rowe is currently a member of the Board of NCAS.  He is a founding member of NCAS and has served on its board since the organization was founded.  He has published several skeptical articles in Skeptical Inquirer and has presented several talks to NCAS on such diverse topics as the Salem Witchcraft Trials, alchemy and forensic science.  Dr. Rowe recently retired as professor of forensic sciences at The George Washington University and has been named professor of forensic sciences emeritus.  He has published over fifty peer-reviewed articles in scholarly journals. Dr. Rowe has AM and PhD degrees in chemistry from Harvard University and a BS degree with highest honors in chemistry from Emory University.  He was awarded a National Science Foundation Fellowship for graduate study. Dr. Rowe is also an honor graduate of the US Army Military Police School’s criminal investigator course and was a credentialed US Army CID investigator.  He served in the US Army Crime Laboratory system as a forensic drug analyst and a forensic serologist. During his military service Dr. Rowe testified as an expert witness at Army courts-martial and processed crime scenes on several US Army posts. Dr. Rowe has also testified as an expert witness in both criminal and civil trials in state and federal jurisdictions across the United States.

SCOTT SNELL

I’m a charter member of NCAS, a past vice president, the current president, and I hope to continue to serve on the NCAS board of directors.  The capabilities that NCAS events producer J. D. Mack has delivered to skeptics, both locally and worldwide online, is a unique gift that I support to the maximum possible extent.  We skeptics are inquirers, and NCAS, perhaps more than any other organization in the world (other skeptics groups, Smithsonian, news media, etc), offers unparalleled opportunities for any event participant to share fully visible moderated comments and questions with other participants and have them conveyed to the speaker.  As moderator/host of our events, I strive for the greatest possible opportunity to share information and questions, both to and from our speakers.  Now, more than ever, we can consult with experts around the world, pose questions to them that they may not have considered before, and see what comes of it. By this, we can also lead by example.  My hope is that more and more people will incorporate skeptical principles in their roles as citizens, students, employees, and even as relatives and friends.  What’s true, and how can we know?  What decisions can we make, despite inevitable uncertainties?  If we skeptics can ask the best questions, we might even pick up some of the slack that much of our news media has sadly dropped in its duty to inform the public.

Coming April 20 and April 25

Skeptical Eye: News from NCAS April 2026

Thoughts on the way to the Moon

view of Earth taken by NASA astronaut and Artemis II Commander Reid Wiseman

Artemis II commander Reid Wiseman (proud son of Baltimore, Maryland) took this photo of Earth after the crew put their ship on course for the Moon.

Except for a slight sliver of sunlight at upper left, the only illumination of Earth is from the full Moon behind the photographer.

Venus is at upper left.

[Artemis II pilot Victor Glover]
"... I think these observances are important, and as we are so far from Earth and looking back at, you know, the beauty of Creation.  I think, for me, one of the really important personal perspectives that I have up here is, I can really see Earth as one thing.  And you know, when I read the Bible, and I look at all of the amazing things that were done for us, who were created, it’s…you, you have this amazing place…this spaceship.  You guys are talking to us because we’re in a spaceship really far from Earth.  But you’re on a spaceship called Earth that was created to give us a place to live in the universe, in the cosmos.  Maybe the distance we are from you makes you think what we’re doing is special.  But we’re the same distance from you, and I’m trying to tell you, just trust me, you are special.  In all of this emptiness, this is a whole bunch of nothing; this thing we call the universe, you have this oasis, this beautiful place that we get to exist together.  I think as we go into Easter Sunday thinking about, you know, all the cultures all around the world, whether you celebrate it or not, whether you believe in God or not, um, this is an opportunity to remember where we are, who we are, and that we are the same thing in that we’ve got to get through this together."

No Blueprint for the Moon:
Navigating the Unknowns of Extraterrestrial Construction


Dr. Caitlin Ahrens

This presentation examines lunar architecture not as science fiction, but as an applied problem in risk management, engineering under uncertainty, and evidence-based design. We will explore what it would actually mean to plan and build structures on the Moon, where our geotechnical data are sparse, environmental hazards are extreme, and many Earth-based design assumptions simply do not hold. We will delve into strategies for site planning in an extreme, unfamiliar environment, where Earth-based assumptions must be rethought. Key challenges discussed include working with limited data, potential hazards from the environment, and the need for adaptable, resilient design solutions in lunar conditions.

Dr. Caitlin Ahrens is an assistant research scientist at NASA Goddard Space Flight Center, and the University of Maryland. She is a member of the Diviner Science Team with the Lunar Reconnaissance Orbiter. In collaboration with Artemis, she serves as a technical support scientist to assist in risk assessments of astronaut, rover, and lander activity at the lunar surface. Dr. Ahrens is Principal Investigator on a recent lunar sustainability work funded by the (former) NASA Office of Technology, Policy and Strategy. She also is a member of the American Society of Civil Engineers (ASCE) working on how lunar architectures should be monitored for hazards, including construction, at the lunar surface.

"Everything you wanted to know about coronaviruses but were afraid to ask."

Laura H. Kahn MD, MPH, MPP, author of One Health and the Politics of COVID-19


Using an interdisciplinary One Health approach, Dr. Laura Kahn will draw upon material from her book, One Health and the Politics of Covid-19, to talk about the history, science, research, and politics of coronaviruses. One Health is the concept that human, animal, plant, environmental, and ecosystem health are linked. This is a relatively new term, but an ancient concept recognized by indigenous peoples around the world.

Coronaviruses are zoonotic viruses, meaning that they originate in non-human animals (i.e., bats) and spread to humans. The most well-known coronaviruses are Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), and Covid-19. Unlike SARS and MERS, which emerged in 2002 and 2012, respectively, Covid-19 appears unusual in some of its clinical manifestations. The gold standard evidence used to prove the natural origins of the earlier coronavirus epidemics is lacking with Covid-19. The origin of this virus remains controversial.


Coronaviruses were first discovered by veterinarians in the early 1930s. Physicians discovered them in the 1960s while studying “the common cold” but assumed that they were merely nuisance microbes. Medical researchers lost interest in them until the shocking appearance of SARS. Gain-of-function research of pandemic potential pathogens, such as SARS, and the possibility that it might have led to Covid-19, raises concerns about the ethics and risks of this type of research. 

Dr. Laura H. Kahn is a physician, policy researcher, educator, and author. For almost 20 years, she was a research scholar in the Program on Science and Global Security at Princeton's School of Public and International Affairs, Princeton University. Her education and training encompass nursing, medicine, public health, and public policy.

A native of California, Dr. Kahn holds a bachelor's degree in nursing from UC Los Angeles, a doctorate in medicine from the Mt. Sinai School of Medicine, a master's degree in public health from Columbia University and a master's degree in public policy from Princeton University. Dr. Kahn is a fellow of the American College of Physicians. In 2007, the New Jersey Chapter of the American College of Physicians awarded her with their highest honor, the Laureate Award. In 2014, the American Association of Public Health Physicians awarded her with a Presidential Award for Meritorious Service, and in 2016, the American Veterinary Epidemiology Society (AVES) awarded her with their highest honor for her work in One Health: the K.F. Meyer-James H. Steele Gold Head Cane Award.

Nate Pedersen on his book 
Pseudoscience:
An Amusing History of Crackpot Ideas and Why We Love Them

image of book: Pseudoscience
From the easily disproved to the wildly speculative, to straight-up hucksterism, Pseudoscience is a romp through much more than bad science—it’s a light-hearted look into why we insist on believing in things such as Big Foot, astrology, and the existence of aliens. Did you know, for example, that you can tell a person’s future by touching their butt? Rumpology. It’s a thing, but not really. Or that Stanley Kubrick made a fake moon landing film for the US government? Except he didn’t. Or that spontaneous human combustion is real? It ain’t, but it can be explained scientifically.   

Pseudoscience is a wild mix of history, pop culture, and good old-fashioned science–that not just entertains, but sheds a little light on why we all love to believe in things we know aren't true. 

 Nate Pedersen is an award-winning nonfiction writer and anthologist living in southern Minnesota.  He is the co-author of Quackery: A Brief History of the Worst Ways to Cure Everything, Patient Zero: A Curious History of the World's Worst Diseases, and his most recent book Pseudoscience: An Amusing History of Crackpot Ideas and Why We Love Them, all from Workman / Hachette.  His website is http://natepedersen.com

MESMERIZED

An Immersive Experiment in Science & Magic

Mesmerized

Saturday, November 15 at 8 p.m.

Capital Hilton, 1001 16th Street Northwest, Washington, DC 20036


The field of experimental psychology arose during a time steeped in wonder and mystery. Spiritualism gained widespread influence, proposing that death was not an end but a transition. Mesmerists claimed to heal all ailments through the laying-on of hands. Early psychologists did not merely react to these remarkable phenomena—they incorporated them into their investigations of the human mind.
In this performance, cognitive scientist & magician Anthony Barnhart, alongside occult aficionado Joe Diamond, explore these mid-19th century curiosities through interactive experiments, psychological illusions, and compelling storytelling.

NCAS Public Lecture Series

A Skeptic's Guide to Mythbusting AI 

James E. Harris, Jr.,  CISSP


Virtually every product and service advertised today claims some use of “AI,” but what is AI, how does it work, and how can it be “de-mythed”? Jim Harris, a Distinguished Engineer and accredited Model Risk Officer, provides a Skeptic’s take on how Large Language Models (LLMs) work, why they fail, and how you can trick them into exposing their weaknesses.

Jim Harris is a board member of NCAS. He graduated in 1994 from North Carolina State University with a BS in Physics. Since that time, he has worked as a hardware engineer for IBM and Silicon Image, a Special Agent for the FBI, a cybersecurity consultant, a tech startup executive, and a Distinguished Engineer and Model Risk Officer for Capital One Financial.

Zimmer contextualizes the recent pandemic as part of a bigger, largely untold story and explores how the aerobiome is an essential part of a living world—a highway through the sky for many species—of which we become a part with every breath we take.  This will be livestreamed on YouTube: https://www.youtube.com/watch?v=UjFrrgH_1V0

A Skeptic's Guide to Mythbusting AI

October 4, 2025 at 1:30 p.m.

James E. Harris, Jr.,  CISSP

Virtually every product and service advertised today claims some use of “AI,” but what is AI, how does it work, and how can it be “de-mythed”? Jim Harris, a Distinguished Engineer and accredited Model Risk Officer, provides a Skeptic’s take on how Large Language Models (LLMs) work, why they fail, and how you can trick them into exposing their weaknesses.
Jim Harris is a board member of NCAS. He graduated in 1994 from North Carolina State University with a BS in Physics. Since that time, he has worked as a hardware engineer for IBM and Silicon Image, a Special Agent for the FBI, a cybersecurity consultant, a tech startup executive, and a Distinguished Engineer and Model Risk Officer for Capital One Financial.

"What is SkepTours?" and "A Skeptic's Guide to Mybusting AI"

What is SkepTours?

Thursday, September 18, 8pm US/ET


Chip Denman, Grace Denman, and Scott Snell will discuss the history of SkepTours, NCAS's long-running project to create a SkepTours Google Map featuring places of interest related to science, pseudoscience, folklore, and just plain weirdness. 

From time to time, NCAS has used the map to conduct leisurely walking tours around Washington, D.C. The next will be Wednesday evening, October 22.

This will be a short discussion, online only. There will be an opportunity for online Q&A.

 YouTube Live Event for Q and A 

Recent Research on the Foundations of Fingerprint Comparison Decisions

Presented by Heidi Eldridge, PhD
Assistant Professor of Forensic Science and Director of Graduate Studies in Crime Scene Investigations
The George Washington University

Wednesday, February 12, 7pm US/Eastern (UTC-05:00)
NCASVideo YouTube Channel:


Fingerprints have long been viewed as infallible -- the "gold standard" when it comes to criminal identification. But recent critical reports and scrutiny have illuminated the fact that fingerprint science, though in use for more than 100 years in the courts, never went through the rigorous process of building a scientific foundation that most scientific endeavors must complete as part of their growing pains. This talk will briefly highlight some of the questions the field is currently grappling with and review the body of research that has sprung up in response.


Dr. Heidi Eldridge
received her MS in Biology from Duke University and her PhD in Forensic Science from the University of Lausanne (Switzerland).  She spent approximately 11 years working in state, local, and regional forensic laboratories where she performed casework in controlled substances, latent prints, and crime scene analysis and reconstruction including bloodstain pattern interpretation, shooting reconstruction, event analysis, biological screening, and serial number restoration. From 2015 to 2022, she was a full-time forensic science researcher at RTI International, where she completed internally- and externally-funded research on the suitability decision in latent prints, establishing a baseline discipline error rate estimate for palmar comparisons, recognizing warning factors for close non-matches in latent prints, and human factors in forensic science. Dr. Eldridge is current Chair of the Friction Ridge Consensus Body of the American Standards Board (ASB) and of the Forensic Science Education Programs Accreditation Commission (FEPAC). She sits on the Boards of Directors of both the International Association for Identification (IAI) and the ASB and is a Fellow of the American Academy of Forensic Sciences (AAFS) and is chair of the Friction Ridge Subcommittee of the Organization of Scientific Area Committees (OSAC) for Forensic Science. Additionally, Dr. Eldridge sits on the Editorial Board of the Journal of Forensic Identification and is a peer-reviewer for several other forensic science journals. Dr. Eldridge is a Certified Latent Print Examiner with the IAI.

Torn From Today's Headlines
By Scott Snell
Year-round Standard Time vs Year-Round Daylight Saving Time vs Clock-Changing
The newly-convened 119th US Congress has introduced the "Sunshine Protection Act of 2025" in the House of Representatives (House Bill 139, Republican co-sponsors) and Senate (Senate Bill 29, bipartisan co-sponsors).  The bills are essentially identical to unsuccessful bills from each of the previous four US Congresses, to make daylight saving time the new, permanent standard time, except for states with areas exempt from daylight saving time; states may choose the standard time for those areas.  (Many state legislatures have also taken up the issue of staying on Standard Time or Daylight Saving Time year-round.  See https://www.ncsl.org/transportation/daylight-saving-time-state-legislation)

In response, the "Coalition for Standard Time" (https://ditchdst.com/) comprising "National Sleep Foundation," "Save Standard Time," and other organizations, has redoubled its advocacy efforts to end Daylight Saving Time.  Their social media channels direct readers to their website's resources, for example, https://srbr.org/advocacy/daylight-saving-time-presskit/

Generally, their message to the public is that the science is clear on the issue: changing the clocks is harmful to health, and permanent DST is harmful to health.  They also note that winter DST was attempted in early 1974 and the US public hated the resulting dark mornings.

However, they don't discuss the successful techniques that Alaskans, Scandanavians, and other residents of long polar night regions use to awaken in darkness and safely travel to work and school.  Those methods weren't used in most of the US during the 1974 DST failure.  Nor do they discuss the situation in Spain, which hasn't been on Standard Time since 1940, and is 2 hours ahead of Standard Time for several months each year.  Spaniards are generally healthy (having the 5th longest life expectancy in the world), despite living on Daylight Saving Time and DST+1.  (Siestas may be part of Spaniards' success, although this is uncommon in their modern urban culture.)  At the very least, this raises questions about how unhealthy a DST lifestyle really is.

Apparently the Coalition is presenting a very simplified version of where the science stands on this issue, and omits viable solutions from their public-facing discussion.

In any case, President Trump has stated that he would support abolishing Daylight Saving Time: https://truthsocial.com/@realDonaldTrump/posts/113647254141876924

Author's comment:
Perhaps it's better to offer the public options, such as, "Yes, you can probably succeed with year-round DST by imitating the successes of Scandanavians who awaken in darkness and safely travel to work and school.  Even if you choose year-round Standard Time instead, you can use those techniques to help people who must still awaken in darkness, such as public transportation employees."  There appears to be a scientific consensus that awakening before sunrise is unhealthy.  The solution is to use artificial lights in the home to simulate sunrise.

On the other hand, maybe expending so much effort just to get some after-work DST sunlight isn't worth the trouble.  That said, year-round Standard Time will mean summer sunset at about 7:30 PM instead of 8:30 PM.  That's not likely to be popular with the public.

My view is that the public should have all the pros and cons of their choices available so they can make an informed decision.  I covered many aspects of this in my November 2023 NCAS talk, which is part of the NCAS YouTube library: https://www.youtube.com/watch?v=4J6QEYSxMjs

Larry Kusche (1940-2024)
Larry David Kusche, CSI Fellow and retired technical document and proposal writer at AlliedSignal/Honeywell Engine Division in Arizona, died on July 22, 2024.  His obituary: https://www.azcentral.com/obituaries/pazs0907396

Skeptics will best remember Kusche for his time (1969-1975) as a research librarian at Arizona State University, when he authored his first book, The Bermuda Triangle Mystery — Solved (Harper & Row, 1975).  Considered the defining work on the subject, he later devoted an entire book to the most famous Triangle incident, The Disappearance of Flight 19 (Harper & Row, 1980).  Perhaps no other alleged "mysteries" have been so effectively debunked as Kusche did for the Triangle, which never again approached the cultural prominence it once had in the early 1970s.

In the back of the very first issue of The Zetetic (from 1976, soon to be renamed as Skeptical Inquirer), published by the newly-formed Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP, forerunner to today's Committee for Skeptical Inquiry), you'll see Kusche listed as a CSICOP Fellow.  Pick up the latest issue (the one with Bill Nye on the cover) and you'll still find him in the list.

Excerpted from Kusche's LinkedIn page:
...wrote the book "The Bermuda Triangle Mystery - Solved," (1975) which exposed the Triangle to be a pseudoscientific/ paranormal fraud based on distorted information.

In 1980 my book "The Disappearance of Flight 19" was a heavily researched account of the loss of the five Avenger torpedo bombers from Fort Lauderdale in 1945.

I am currently developing a website on the Triangle, as it has risen again as a popular topic. Am analyzing NTSB reports of accidents in the area that are being reported as supposedly mysterious.

Interesting that Kusche perceived that the Bermuda Triangle had made a "comeback."  (I don't know when he wrote this LinkedIn profile.)

Forty years after his first book, he wrote a retrospective (and, as it turned out, final) article for Skeptical Inquirer:

Comment by Scott Snell:
Several months ago, I was at a social occasion with colleagues from Goddard Space Flight Center.  The topic of skepticism came up (probably my choice) with a friend/coworker of one of the NCAS board members.  We were amused to discover that both of us followed the same pathway into the subject: as kids (roughly the same age), we were fascinated by UFOs, Bigfoot, ESP, etc.  And our first introduction to skepticism wasn't Sagan or Randi or Klass...it was Kusche's The Bermuda Triangle Mystery — Solved.  From then on, both of us eventually found the other skeptical books and Skeptical Inquirer.

Today, I emailed him with the news of Kusche's passing.  He thanked me and said he'll start reading the book again.

I had the pleasure of meeting Kusche at a CSI conference ("UFOs: The Space-Age Mythology," October 2009 in Tucson, Arizona).  He was one of the attendees, not a presenter.  I'm glad I happened to glance at his name tag, otherwise I might never have realized he was there.  I let him know how grateful I was for his book...what an eye-opener (actually mind-opener) it was for my young self.

He kindly offered to autograph my copy of his book if I'd ship it to him.  And he included a free signed copy of his Flight 19 book.  (He didn't ship them immediately...it turned out that he held onto the books a little longer so he could autograph them on December 5, the anniversary of the Flight 19 incident!)

My last contact with him was in October 2016, by email:

Dear Mr. Kusche,

I'm Scott Snell of the National Capital Area Skeptics (ncas.org).  I doubt you'll remember meeting me at the October 2009 CSI UFO workshop in Tucson...in any case I enjoyed meeting you and appreciated your autographing my copies of your books, including the Flight 19 book that you provided as a gift.

I'm writing to you today because I'll be providing the results of your research on the USS Cyclops case to tourists [on an NCAS "SkepTour" in Washington, DC] later this week.  If possible, I'd like to include your views on the following article from Popular Science, June, 1929:

https://books.google.com/books?id=XSgDAAAAMBAJ&pg=PA15&hl=en#v=onepage&q&f=false

Author Reck also believes the storm is responsible for the loss of Cyclops.  But even more interesting is that he apparently reviewed the log of Amolco, stating that Cyclops was sighted on the evening of the 9th!

https://books.google.com/books?id=XSgDAAAAMBAJ&lpg=PA15&pg=PA137#v=onepage&q&f=false

If true, this is an independent confirmation that Cyclops was approaching Virginia at the time of the storm.

This 1920 book also provides information about the log entry:

https://books.google.com/books?id=m_ZopT3od1IC&pg=PA25&lpg=PA25#v=onepage&q&f=false

There are obvious errors: "U. S. S. Amalco" for one.  But these could simply be garbled details of worthwhile information.

What are your thoughts about this?

Regards,
Scott Snell

Kusche replied:

Hello Scott,

Thank you for the material on the Cyclops.
I had some info on the storm and the Amolco in the book, but not the source that you sent me.

I’ll get back to you with more info later.

Larry Kusche

I never heard back from him.

The 1929 article was significant because it was the first to establish that a severe storm was impacting the Eastern US seaboard.  (Kusche had been unaware of this article when he independently came to the same conclusion during research for his book.)

However, the article's claim that the Amolco's log indicated that Cyclops was sighted is false.  See U.S.S. Cyclops (Heritage Books, 2010) by Marvin W. Barrash, the October 2018 NCAS speaker.
