Mysterious disappearance of UFO-linked Air Force general sparks search

Thinking about it again, I don't think Tom Delonge referred to any sort of "extraction system", at all. What he said is more in line with the concept of tapping into ZPE, which is a different concept and have a different connotation, and may even imply different scientific purposes than harnessing infinite/massive amounts of energy.
...it's from Tom DeLonge, who is the main source of the UFO rumours about McCasland: [Quoting The Daily Mail]
External Quote:
He [DeLonge] claimed that the US government and contractor groups already possess free energy technology... ...that could make conventional energy sources obsolete, stating: 'One inch of air could power the U.S. for hundreds of years.'

"One inch of air" isn't a measurement of volume; even at the most basic semantic level this is an unscientific claim.
 
So....he's lying.

That's a bit harsh, he's not lying, he's....selling. And, I would argue he may have been selling something he thought was indeed possible if not already in existence. Let's remember, DeLong has no collage background that I'm aware of, he spent most of his life as a musician. Not at all saying he's dumb, just that he, like me and lot's of people, may not have the physics chops to completely understand if ZPE is a thing or not.

More importantly, at the time of the emails, DeLong was in contact with at least 1 PhD level physicists and probably 2. DeLong co-founded TTSA with Jim Semivan and Hal Puthoff. Puthoff is a physicist and his long time collaborator and side-kick, Eric Davis, is also a physicist.

Davis and Puthoff were also involved in Bigelow's various endeavors like NIDS and BAASS. Puthoff's EarthTech company was contracted by BAASS to provide papers on possible future tech to fulfill the contract to the government run AAWSAP. Puthoff wrote a paper on space-time modification, while Davis wrote a paper on anti-gravity, something else DeLong often mentioned, and he wrote a paper on...Vacuum Energy otherwise known as Zero Point Energy. From the list of DIRDs (the official name for the papers they and others wrote):

There is no doubt that TTSA turned into a bit of a hustle and DeLong stood to gain financially from it. And it is clear that DeLong, both in the McCasland emails and other instances, including TJR show, made lots of hyped up claims in a likely attempt to make TTSA more legitimate. But I think it's also likely that DeLong had 2 PhD level physicists priming him about things like anit-gravity and Zero Point Energy. In his mind these are guys that had worked for the CIA, the DoD and had top secret clearance. Davis had written, and sold, papers to the USAF detailing teleportation and only a few years before DeLong was hyping TTSA in emails, Davis had written a government sponsored official DIRD papers on ZPE (Vacuum Energy).

DeLong may have well believed ZPE was real, or at least eminently possible. So, not lying, just selling something he thought could be real.
 
"One inch of air" isn't a measurement of volume; even at the most basic semantic level this is an unscientific claim.

technically he says "so like one inch of air.. kind of thing". he's talking about atoms. like "splitting atoms", but not splitting atoms? hard for me to follow.. but hes talking about the number of atoms in that inch of air is how i decipher it.

You quoted Mick West's post about Delonge's claim that free energy technology is possessed by the US government, which BTW has nothing whatsoever to do with his "one inch of air" metaphor.

Would you please give me just one reference to where and when he explicitly said "free energy"? Thanks!

Though he doesn't use the term "free energy", in this interview with Joe Rogan Tom DeLonge appears to think ZPE/ vacuum energy is a workable technology, and we have it (or are near it) and it's not being hidden from us as such, its being hidden from the aliens. He uses the "one inch of air" example (I don't think it's a metaphor).

Again, opinions -- like yours on how related to free energy are Delonge's comments -- can't be taken to assume that once a upon a time in his life he explicitly stated that the US Government possesses free energy technology, like what the Daily Mail did on that article that Mick West referred to on his post and you quoted.

I think it's now more than enough time to move on to what really matters to the thread's topic.

I agree in that ZPE energy is a non-existent technology. The issue came up because some people seem to believe (at least according to The Daily Mail) that William McCasland is somehow connected to ZPE research, and knows stuff about alien spacecraft, and this is somehow linked to his disappearance. Part of their reasoning for this might be because McCasland had links with Tom Delonge, who makes unusual claims about ZPE and alien spacecraft.

If it weren't for these conspiracy theories, I doubt we'd be discussing McCasland's disappearance on Metabunk. Approx. 360,000 adults go missing in the US each year; most are soon found (or have volitionally "disappeared" for their own reasons) but sadly some are not. But we haven't discussed any of those other disappearances (IIRC), although each and every case might be as puzzling (and potentially as saddening) as this one.

From the sound of it he doesn't really have a clue. ZPE is not 'an electromagnetic wave'. It is basically the minimum energy state of the vacuum....which is not zero. It is basically similar to the phenomenon of virtual particles, which derive energy from the Heisenberg Uncertainty Principle. It exists in the form of virtual pairs...matter and antimatter...that cancel each other out in a very brief period of time. If the matter in the virtual pair did not recombine with the antimatter then you'd end up with antimatter accumulating everywhere....which is not happening....so there is zero evidence that any regular natural process can 'extract' this energy. In fact the only natural process that can separate the pair is the the gravity and event horizon of a black hole....and that phenomenon is the basis of Hawking radiation.

That extraction is not 'free energy'. It is basically converting the mass of the black hole into energy....so the black hole shrinks over time.

So basically you need a black hole to extract this energy. And the problem is, you'd put more energy into creating a black hole, even a mini one, for this extraction than you'd get out of it. In fact, using Hawking radiation to extract radiation from a black hole is basically extracting the energy you put into making the black hole. There is no net gain, and you are unlikely to capture every particle emitted so the whole thing is futile.

Which is why 'harnessing' ZPE is really the quantum equivalent of perpetual energy machines. It is all hyperbole.
 
Thinking about it again, I don't think Tom Delonge referred to any sort of "extraction system", at all. What he said is more in line with the concept of tapping into ZPE, which is a different concept and have a different connotation, and may even imply different scientific purposes than harnessing infinite/massive amounts of energy.

He's probably thinking of the Casimir effect....

https://en.wikipedia.org/wiki/Casimir_effect

I can do no better than quote what Google AI has to say....

The Casimir effect cannot be used to extract limitless or "free" energy from the vacuum. While it generates a measurable, attractive force between closely spaced plates due to quantum vacuum fluctuations, harvesting this energy requires more work to separate the plates again than is released, making it a conservative, non-perpetual system.

Key Details on Casimir Energy Extraction:
  • Fundamental Limitation: The vacuum is already in its lowest possible energy state; the Casimir force allows you to extract energy only by moving to an even lower state, which is impossible to do indefinitely.
  • One-time Work: You can extract a single burst of energy as plates move together, similar to a spring closing, but you must invest equal or greater energy to re-separate them.
  • Not "Free" Energy: Any device using the Casimir effect to generate motion would need to overcome the force to reset, resulting in a net energy loss or zero gain.
  • Applications: It is primarily studied for use in Microelectromechanical Systems (MEMS) or Nanoelectromechanical Systems (NEMS) where tiny, short-range forces are utilized, not for power generation.
    Reddit +4
Although the Dynamic Casimir Effect can produce photons from the vacuum, the energy required to rapidly move the boundary conditions (e.g., mirrors) far exceeds the energy obtained.
 
Yea, odd coincidence in most of the lyrics that I could grasp (there are words that I might have to hear with headphones and upper volume). And the dark atmosphere it conveys is remarkable too. I sincerely hope everything shifts to the best for Susan McCasland.

As we're getting off-topic for just a moment here:
On a side note, I have just listened to Susan's performance on the Band Twisted Mojo. According to my personal appreciation, had she a more strong and genuine approach as a singer, I'd dare say Sonja Kristina (Curved Air) might be one of her main artistic influences. Because, for some reason the way she (Susan) makes the fermata (holding the notes) sounded to me slightly reminiscent of her in terms of style.
That is interesting, and sad, too. One wonders about many things.. The video, with all of the stars…
The song reminds me a bit of Joan Baez..

Maybe a bit of a language issue. E desculpas por favor, I'm not at all questioning your command of English or knowledge of this stuff. My command of Portugues is limited to "bom dia", "gelo" and "caracois", though my son is semi-fluent. Just some background in how us native English speakers are reading some of this.

To clarify, "free energy" is a catch-all phrase for any number of systems that supposedly produce more energy than is input to the system. I think a more accurate term often used is "over unity". In the old days of mechanical devices, this was known as "perpetual motion machines". Now in the days of electricity, various supposed inventors have proposed devices that end up producing more energy than they take in, thus they are said to be "over unity". Both over unity and perpetual motion machines violate the known laws of physics.

Any Over Unity system that creates more energy than it takes in, is said to create free energy.

Zero Point Energy, also referred to as Vacuum Energy, is an over unity system that some fringe physicists think might be possible. As it's over unity, it is a version of free energy. So, if DeLong or anyone else mentions Zero Point Energy or Vacuum Energy they are talking about Free Energy. It's the same thing.


I think we all agree, that as of now, there is NO evidence of McCasland talking about "free energy" in any form. DeLong talks about Zero Point Energy, so that's the same as free energy.

Bom mesmo :D
 
In scientific usage Vacuum Energy is by far the most common. I haven't seen an English language scientific paper use 'zero-point-energy' in a generation now.

Vacuum energy in physics is commonly denoted by E0 (can't figure out how to do a subscript atm)

I think it is a very lay description of "one cubic inch of space." Which current science puts between 10e-14 and 10e108 joules per cubic inch

Depending on the Planck energy cutoff and other factors, the quantum vacuum energy contribution to the effective cosmological constant is calculated to be between 50 and as many as 120 orders of magnitude greater than has actually been observed,[1][2] a state of affairs described by physicists as "the largest discrepancy between theory and experiment in all of science"[1] and "probably the worst theoretical prediction in the history of physics".[3]
 
New York Post: Hundreds of New Mexico locals asked to turn over home security in search for missing retired Air Force general, UFO expert
Investigators contacted the Albuquerque homeowners to gather the home camera footage and information in an effort to track down William Neil McCasland, 68, who vanished without a trace from his home on Feb. 28, according to the Bernalillo County Sheriff's Office.

"Investigators have contacted more than 600 homeowners in the neighborhood near Mr. McCasland's residence to request security camera footage or information," a police spokesperson told The Post.
 
I used to know a KC-135 crew chief who'd tell people they routinely refueled UFOs in flight just to see if they'd buy it.

Was about to post something similar.
Testing the level of initiation in the audience is not only essential when communicating - it's also fun.

Drop the odd shibboleth here and there and see who's still talking about UFO's and ET.
Mrs McCasland (as the brightest person in the room) almost certainly understands this.
 
UFO expert? Not going click on that.

I couldn't stop myself. As one would expect, ALL the UFO references come from a less than reliable source, in this case our 'ol buddy Ross:

External Quote:

"This is a man with some of the most sensitive secrets of the United States in his head," journalist Ross Coulthart said in the latest edition of his "Reality Check" podcast, adding that McCasland possesses deep knowledge about what the US government might be hiding regarding extraterrestrials.

"The timing is screechingly relevant. The fact that Gen. Neil McCasland has disappeared off the face of the earth is a grave national security crisis for the United States of America."

His disappearance came just days after President Trump announced in a Truth Social post that he was directing the Department of Defense to prepare the release of files related to UFOs and extraterrestrial life.

During his military career, McCasland headed up research at Wright Patterson Air Force Base — a role in which he oversaw classified space weapons programs, according to Coulthart.

The base, near Dayton, Ohio, is rumored to be in possession of extraterrestrial debris allegedly from UFO hotspot Roswell, New Mexico.
https://nypost.com/2026/03/10/us-ne...al-ufo-expert-grave-national-security-crisis/

Notice that even with a UFO expert like Coulthart using this guy's disappearance as some "schreechingly relevant" OMG! fodder for his podcast , he's still forced to use words like "might". Because he, and the rest of them, have no evidence that McCasland had any knowledge of aliens.

Updated Timeline and Description in Search for William "Neil" McCasland

The Bernalillo County Sheriff's Office (BCSO) continues the missing person investigation into the disappearance of 68-year-old William "Neil" McCasland, last known to have been at or near his residence in the area of Quail Run Court NE on the morning of Friday, February 27, 2026. A Silver Alert remains in effect, and Mr. McCasland remains missing.

As previously stated, Mr. McCasland is a retired U.S. Air Force general. BCSO is the lead investigative agency and continues to coordinate with partner agencies in support of investigative follow up and search operations, including the FBI Albuquerque Field Office when tools, tactics, or techniques can assist. Search resources are coordinated through the New Mexico Department of Public Safety and New Mexico State Police Search and Rescue system, with volunteer search teams assisting as requested. Tomorrow marks two weeks since his disappearance.

BCSO is releasing the following verified timeline to provide clarity on what is known. On February 27 at approximately 10:00 a.m., a repairman was at the residence and interacted with Mr. McCasland. At approximately 11:10 a.m., Mrs. McCasland Wilkerson left the home for a medical appointment. At approximately 12:04 p.m., she returned home and Mr. McCasland was not there. His phone, prescription glasses, and wearable devices were located at the residence. Mrs. McCasland Wilkerson began attempting to locate Mr. McCasland and contacted family and friends. At approximately 3:07 p.m., she reported him missing and the investigation began immediately.

As the investigation has progressed, BCSO has identified items believed to be unaccounted for from the residence. Investigators believe Mr. McCasland may have been wearing the shirt shown in the attached photo. The photo depicts Mr. McCasland wearing a light green, long sleeve button-up outdoor shirt. Additional items believed to be missing include his hiking boots, wallet, and a .38 caliber revolver with a leather holster.

Investigators also located a gray U.S. Air Force sweatshirt approximately 1.25 miles east of the residence on Saturday, March 7. The item was collected and processed. No blood was detected during initial processing, and additional analysis is pending. The sweatshirt has not been confirmed by family or friends to be associated with Mr. McCasland; however, it prompted an additional targeted search effort in the area.

BCSO continues to pursue all credible leads and follow up on every tip received. While there is currently no evidence indicating foul play, investigators are examining all available information as the case remains active. Investigators have expanded a neighborhood canvass to more than 700 homes, requesting security video and information. Additional search efforts have included drone operations, helicopter support, ground searches with Search and Rescue teams, and K 9 searches. To date, BCSO has not received any confirmed sighting or confirmed video showing Mr. McCasland leaving the area or indicating a direction of travel. Search efforts and investigative follow up are ongoing.

The Silver Alert was issued based on information available early in the investigation that indicated Mr. McCasland could be at some level of risk and that additional public assistance was needed to locate him. Due to privacy laws, BCSO will not release medical details or speculate about his state of mind.

BCSO is again asking anyone in the area to check and submit security camera footage from Friday, February 27 and Saturday, February 28, particularly between 9:00 a.m. and 2:00 p.m. in and around Quail Run Court NE and routes leading away from the neighborhood. If you were in the foothills or on trails February 27 to 28, please review any GoPro or phone footage and submit anything that may help.

Video and photos can be uploaded here:

It's depressing how many google hits "screechingly relevant" gets. Yes, they're all Coulthart.

Are we to assume that bird screeching or brake screeching is a metaphor for relevance?

I think the metaphor relates to something that is loud, urgent and (in their eyes (ears?) ), very uncomfortable to hear for most.
 
New York Post: Possible X account of missing general William McCasland claimed fellow general was murdered over nuclear material
External Quote:
McCasland, 68, went missing from his Albuquerque, NM, home on Feb. 27 — which is the same day that the person behind a conspicuously credentialed X account centered on spacecraft and advanced science made their last post.

The account @tmbspaceships claims to be run by a "retired 38-year active duty" United States Air Force with a PhD in engineering — listing the Air Force Institute of Technology (AFIT), the Air Education Training Command (AETC), and Air Force Material Command (AETC) as places they've worked.

Both the AFIT and AFMC are located at Wright-Patterson Air Force Base, which McCasland ran from 2011 to 2013. He attended the Air War College during his 34-year career, which is a subordinate to the AETC. McCasland attained a PhD in Astronautical Engineering from MIT in 1988.

The account shockingly claimed just months before McCasland's disappearance that Maj. Gen. John Rossi, who allegedly committed suicide in 2016, was actually murdered because of refusal to hand over nuclear material to private contractors.
I originally saw the claim that McCasland = tmbspaceships in this Substack post, which was posted to Reddit:

The Sentinel Briefing: THE DEAD DROP: An Anonymous X Account Went Silent the Day the General Vanished. We Found What It Left Behind. (r/UFOs thread made by same person)

The X account's last post was indeed made on February 27. You can see this without needing to log in by using Nitter: https://nitter.net/TMBSPACESHIPS/with_replies

However, Steven Greenstreet discussed being blocked by the account. In the replies, others claimed to have been blocked days after McCasland's disappearance, likely debunking this coincidence that the New York Post ran with. There's also some discussion of an X user making the connection as early as March 4, and sending a tip to Ashton Forbes:

1. Steven Greenstreet has clipped out a 1m56s portion of this podcast that was streamed live on March 7. I have timestamped it to where it starts, at 10:26:



2. I don't know anything about it. But it is "confirmed" by an AI-generated summary on a Brave search for "Ashton Forbes MH370":

Ashton Forbes is an independent investigator and former professional consultant who gained prominence for his unconventional theories about the disappearance of Malaysia Airlines Flight MH370 in 2014. He rose to public attention through his deep-dive analysis of leaked military drone footage and thermal imaging, which he claims show the aircraft being surrounded by mysterious orbs and vanishing into a portal-like phenomenon.

Forbes has proposed several speculative explanations for MH370's disappearance, including teleportation, wormholes, and the use of directed-energy weapons or plasma orb technology. He argues that the official narrative—suggesting a mechanical failure or pilot-induced disappearance—does not align with the evidence he has uncovered. His theories are centered around a viral video allegedly showing the plane being escorted through an interdimensional portal, which he claims is authentic and suppressed by governments.

His work has been featured in multiple podcasts, including The Resilient Show (Episode 074, September 2025), Blurry Creatures (Episode 240, May 2024), and Deep Dive MH370, where he discusses Exotic Vacuum Objects (EVOs) and advanced physics concepts. Despite widespread skepticism from aviation experts and debunkers—some of whom claim the video effects are from a video game—Forbes maintains that his evidence is legitimate and that a global cover-up involving elite technological programs, possibly linked to Diego Garcia Military Base, is responsible for concealing the truth.

Forbes leads a community-driven initiative called MH370x, dedicated to achieving "true disclosure" of the events surrounding MH370. His work continues to attract global attention, though it remains controversial and unverified by mainstream scientific or aviation authorities.

That is citing lots of podcast pages, such as this one:

Biography


Ashton Forbes is an independent citizen journalist and investigator focused on the enduring mystery of Malaysia Airlines Flight MH370. He rose to prominence through his deep-dive analysis of video evidence and is best known for proposing bold, unconventional theories—including advanced physics concepts like wormholes—as possible explanations for the disappearance of MH370
 
I somehow missed this bit, mentioed above, until I saw it in a newer online story today:

https://www.scrippsnews.com/us-news...ce-of-retired-air-force-general-in-new-mexico

That does not read like an abduction, that reads like going off for a hike. I am not sure evil aliens, MIBs or government agents involved in an abduction would allow him to take his firearm, or gt his wallet and his hiking boots.

I am hopeful that the inclusion of the firearm is just a man accustomed to having one carrying it against need in the area where he planned to hike, but I confess that coupled to his disappearance it worries me. I hope for his safety
 
I originally saw the claim that McCasland = tmbspaceships in this Substack post, which was posted to Reddit:

No evidence has been offered that General McCasland is the author of/ connected with @TMBSpaceships, other than the account going silent the day he disappeared and the claimed credentials of the author.
I expect lots of other social media accounts went silent the same day; many go silent every day for all sorts of reasons.
It is not unknown for for social media accounts/ blogs etc. etc. to be written by people claiming, or implying, that they are someone else.
Perhaps less common on major platforms than it once was, but in the past many celebrities, entertainers, politicians etc. have found "they" have accounts which they were not actually responsible for.
If someone goes missing, it would seem sensible nowadays for police to check that person's phone/ other online devices for possible clues, but don't know if this has been the case re. McCasland.

If there is a claimed connection between McCasland and @TMBSpaceships, we should look at @TMBSpaceships.
McCasland has a PhD in astronautical engineering, (USAF biography https://www.af.mil/About-Us/Biographies/Display/Article/104776/major-general-william-n-mccasland/). He almost certainly has a good grasp of many concepts in physics and engineering generally.

Much of the material at @TMBSpaceships is nonsensical, with a few "diagrams" that resemble outsider art more than anything to do with physics or engineering.

So that just about wraps it up for optical computers, fly-by-light, lasers, Breakthrough Starshot-type proposals for interstellar flight, fibreoptic data links (through which the overwhelming majority of data are transmitted around the world), measuring/ mitigating against gamma radiation, vast areas of physics. Engineers should not focus on these. Might make some discussions about relativity and quantum mechanics difficult. Some of these fields might have some relevance to engineering advanced spacecraft...

(1) Lightning is not "always available in locality", this is absurd. (2) Harnessing and storing the energy from lightning might be difficult.

The content of TMBSpaceships will not be of interest to foreign intelligence agencies. There is no conceivable reason why any agency of the US government would want to use sinister means to silence the author. TMBSpaceship's content doesn't discuss real concepts in technology or physics in a meaningful way.

New York Post: Possible X account of missing general William McCasland claimed fellow general was murdered over nuclear material
External Quote:
McCasland, 68, went missing from his Albuquerque, NM, home on Feb. 27 — which is the same day that the person behind a conspicuously credentialed X account centered on spacecraft and advanced science made their last post.

The account @tmbspaceships claims to be run by a "retired 38-year active duty" United States Air Force with a PhD in engineering — listing the Air Force Institute of Technology (AFIT), the Air Education Training Command (AETC), and Air Force Material Command (AETC) as places they've worked.

Both the AFIT and AFMC are located at Wright-Patterson Air Force Base, which McCasland ran from 2011 to 2013. He attended the Air War College during his 34-year career, which is a subordinate to the AETC. McCasland attained a PhD in Astronautical Engineering from MIT in 1988.

The account shockingly claimed just months before McCasland's disappearance that Maj. Gen. John Rossi, who allegedly committed suicide in 2016, was actually murdered because of refusal to hand over nuclear material to private contractors.
I originally saw the claim that McCasland = tmbspaceships in this Substack post, which was posted to Reddit:

The Sentinel Briefing: THE DEAD DROP: An Anonymous X Account Went Silent the Day the General Vanished. We Found What It Left Behind. (r/UFOs thread made by same person)


Sentinel's been posting patently absurd AI prose stuff about 3I/Atlas for months now, I'm fairly skeptical about any claims they make.
 
Not taking his phone, though?
I'm not sure of his usual hiking preferences, but if he was going someplace like up a canyon, there may be no service available there anyway. It's desert and mountain, so I'd not be surprised if he expected to be out of range.
