秘書官アイリスの都市伝説手帳～Urban Legend Notebook of Secretary Iris～

I am Iris.
Urban legends are not mere fabrications—
I am the storyteller who traces the unspoken truths with you.

Note: This article is based on information publicly available as of June 7, 2026.

Because it concerns a real person who remains missing, it does not claim that his disappearance involved abduction, criminal activity, government agencies, UAP, or extraterrestrial beings.

It separates official statements, confirmed career history, the family’s explanation, and later urban-legend narratives to examine how a real missing-person case became connected to UFO secrecy lore.

A Real Disappearance and the “Holy Ground” of UFO Secrecy

On February 27, 2026, a retired military officer disappeared from the area of his home in Albuquerque, New Mexico.

His name was William “Neil” McCasland.

He was a 68-year-old retired U.S. Air Force major general and an engineer with a doctorate in astronautical engineering.

From 2011 to 2013, he commanded the Air Force Research Laboratory, or AFRL, which is headquartered at Wright-Patterson Air Force Base in Ohio.

For people familiar with UFO history, the name Wright-Patterson immediately evokes a series of powerful associations.

Project Sign.

Project Grudge.

Project Blue Book.

Alleged wreckage transferred from Roswell.

And the long-standing urban legend of recovered vehicles or non-human bodies stored in a location popularly called Hangar 18.

When a former commander of an advanced research organization headquartered at that base suddenly vanished, an urban legend began forming almost immediately.

Did he know something?

Had he been connected to UFO secrets?

Was his disappearance related to classified technology or knowledge that could not be made public?

Before those questions can be examined, the geography and the official roles must be corrected.

McCasland did not disappear from Wright-Patterson Air Force Base.

He disappeared from the area of his residence in Albuquerque.

He was also not the installation commander of Wright-Patterson itself.

He commanded AFRL, a research organization headquartered at the base.

The difference may appear small, but it is essential.

Shift the facts slightly, and a real missing-person case becomes the story of a general who “vanished from a UFO base.”

The Confirmed Timeline of February 27

According to a timeline released by the Bernalillo County Sheriff’s Office, a repairman interacted with McCasland at his residence at approximately 10:00 a.m. on February 27.

At approximately 11:10 a.m., his wife, Susan McCasland Wilkerson, left for a medical appointment.

She returned at approximately 12:04 p.m. and found that he was no longer at home.

His phone, prescription glasses, and wearable devices remained at the residence.

After contacting family members and friends, she reported him missing at approximately 3:07 p.m.

Items initially believed to be unaccounted for included his wallet, hiking boots, and a .38-caliber revolver in a leather holster.

Authorities later reported locating clothing and hiking boots at another property.

His wallet, revolver, holster, and a red backpack remained unaccounted for in the early public updates.

A gray U.S. Air Force sweatshirt was also found approximately 1.25 miles east of the residence.

The family did not confirm that it belonged to McCasland, and initial processing detected no blood.

Ground teams, K9 units, drones, and helicopters were used in the search.

Investigators canvassed hundreds of homes and collected surveillance footage.

The FBI’s Albuquerque Field Office assisted when investigative tools or techniques were useful, while the sheriff’s office remained the lead agency.

No confirmed sighting or video established McCasland’s direction of travel.

Authorities stated that they were examining every credible possibility.

At the same time, the initial official updates stated that investigators had found no evidence indicating foul play.

That is the publicly confirmed outline.

There are many unanswered questions within it.

But unanswered questions are not themselves evidence of UFO involvement.

What the Silver Alert Does—and Does Not—Mean

A Silver Alert was issued following McCasland’s disappearance.

Such alerts are used to seek public assistance when an older missing person may face an elevated risk to their safety.

The sheriff’s office explained that information available early in the investigation suggested some level of risk and justified wider public assistance.

Reports also stated that McCasland had previously described experiencing a form of mental fog.

At the same time, investigators said there was no evidence establishing that he had been disoriented or confused when he disappeared.

His family rejected online claims that he had dementia.

Neither extreme should be adopted without evidence.

Health information does not establish why he disappeared.

His former access to classified programs does not establish that a crime or intelligence operation occurred.

Neither explanation has been confirmed.

Who Was William Neil McCasland?

His disappearance drew attention not merely because he had held a high military rank.

McCasland graduated from the U.S. Air Force Academy with a degree in astronautical engineering and earned graduate degrees from the Massachusetts Institute of Technology, including a doctorate in astronautical engineering.

His Air Force career included roles involving space research, satellite programs, acquisition, operations, and the National Reconnaissance Office.

His assignments included:

engineering and leadership positions in special space projects,

chief engineer for the Navstar GPS Joint Program Office,

director of the Space Based Laser Project Office,

director of AFRL’s Space Vehicles Directorate,

Director of Space Acquisition for the Air Force,

Director of Special Programs within the Department of Defense,

and Commander of the Air Force Research Laboratory.

The public career record places him close to some of the United States’ most advanced aerospace, surveillance, directed-energy, and defense-research programs.

AFRL is a major science and technology research organization for the Department of the Air Force.

Its work spans aerospace systems, propulsion, sensors, materials, information technology, directed energy, space vehicles, and human performance.

Some of that work naturally intersects with national security and classified information.

It is therefore understandable that some observers assume McCasland knew things unavailable to the general public.

But a boundary remains necessary.

Experience in classified military research is not evidence of knowledge about extraterrestrial material.

Past access to secrets is not evidence that his disappearance was caused by those secrets.

There is a wide gap between “he may have known classified information” and “he disappeared because of it.”

Wright-Patterson’s Documented UFO History

Why is Wright-Patterson so closely linked with UFO secrecy?

Part of the answer lies in official history rather than folklore.

From 1947 through 1969, the U.S. Air Force investigated reports of unidentified flying objects.

The investigations included Project Sign, Project Grudge, and Project Blue Book.

They were conducted through organizations located at Wright-Patterson Air Force Base.

According to the Air Force, Project Blue Book received 12,618 reports.

Of those, 701 remained classified as unidentified.

The official Air Force conclusions were that:

no investigated UFO was shown to threaten national security,

no evidence demonstrated technology beyond contemporary scientific knowledge,

and no evidence established that unidentified sightings represented extraterrestrial vehicles.

After Blue Book ended, its records were transferred to the National Archives for public examination.

Wright-Patterson’s role in military UFO investigation is therefore real.

The base did not merely appear in later conspiracy books.

It genuinely served as an institutional center where unusual aerial reports were collected and assessed.

But the official records do not establish that extraterrestrial beings or vehicles were confirmed there.

This distinction gives the legend its durability.

The government truly investigated UFOs.

Hundreds of reports remained unidentified.

But the official conclusion rejected extraterrestrial explanations.

The space between investigation and unresolved cases allowed suspicion to survive.

Hangar 18 and the Roswell Story

In urban-legend circles, material recovered near Roswell in 1947 was allegedly transported to Wright-Patterson.

Stories describe unusual wreckage, advanced materials, and even non-human bodies being stored in a secret location commonly called Hangar 18.

These claims have not been officially confirmed.

The Air Force’s Roswell reports attributed the recovered material to a classified balloon project.

Later stories involving bodies were explained as possible combinations of military accidents, high-altitude research, anthropomorphic test dummies, and memories from different periods.

The National Archives states that its records do not establish that extraterrestrial visitors or equipment were stored at Wright-Patterson.

Accepting or rejecting the official explanations is a separate question.

The public record does not confirm that an extraterrestrial craft or bodies were transferred to the base.

Yet Wright-Patterson had a genuine UFO-investigation history.

It hosted advanced aerospace research.

Some of its activities were classified.

Roswell lore therefore found an ideal destination.

Within the culture of urban legends, Wright-Patterson became the place where the government was imagined to bring mysteries from the sky.

McCasland’s Limited Contact with the UFO Community

After his disappearance, McCasland’s connection to the UFO community also received attention.

According to his wife, he briefly performed unpaid consulting work after retirement for activities connected to musician Tom DeLonge.

She described the role as providing military, scientific, and technical realism for fiction and media projects.

She rejected claims that McCasland possessed special knowledge of alleged extraterrestrial bodies or Roswell wreckage stored at Wright-Patterson.

Although he had accessed highly classified programs during his career, she noted that he had retired approximately 13 years earlier and considered it unlikely that anyone would abduct him for outdated secrets.

This distinction is important.

The family did not deny that a limited association existed.

But that narrow association expanded online into much larger descriptions.

A short advisory role became evidence that he was a UFO insider.

A former research commander became a keeper of alien secrets.

A connection created for realism in fiction became part of a real-world disappearance narrative.

The confirmed fact remained small.

The story built around it became enormous.

Why Did This Case Become an Urban Legend?

Several elements made McCasland’s disappearance especially vulnerable to mythmaking.

The first was his career.

He was an astronautical engineer, a major general, and a leader with experience in space acquisition, reconnaissance, special programs, and AFRL.

He could easily be imagined as a person who knew more than the public.

The second was institutional symbolism.

AFRL is headquartered at Wright-Patterson, a base linked to Project Blue Book and decades of Roswell and Hangar 18 lore.

The third was the unexplained disappearance.

He left behind his phone, glasses, and wearable devices, while no confirmed video established where he went.

The fourth was his limited contact with UFO-related media activity.

A brief post-retirement association was combined with his military career.

The fifth was the cultural moment.

The disappearance occurred during renewed public interest in UAP disclosure, government records, whistleblowers, and advanced technology.

Placed together, separate facts appear to form a single narrative.

A general who knew space secrets.

A legendary UFO base.

A sudden disappearance.

Electronic devices left behind.

A missing wallet and firearm.

A government that supposedly refuses to explain.

But that final element must be corrected.

The case is led by a local sheriff’s office, not by a secret military organization.

Investigators released a timeline and details about the search.

The family publicly addressed rumors.

Unknown information remains, but “not yet known” is not the same as “hidden by the government.”

The 2026 List of “Missing Scientists”

During the spring of 2026, McCasland’s disappearance was increasingly grouped with deaths and disappearances involving other researchers, engineers, and military personnel.

Space programs.

Nuclear research.

Advanced materials.

Propulsion.

Defense technology.

UFOs and UAP.

People with some connection to these areas were placed onto lists, and a narrative emerged that scientists with access to sensitive knowledge were being removed.

The theory moved beyond online forums and received attention in parts of the media and political world.

But the cases included on such lists differ greatly in time, location, occupation, and circumstance.

Illness.

Accidents.

Cases officially classified as suicide.

Confirmed criminal violence.

Unresolved disappearances.

A broad category such as “connected to advanced technology or national security” can create a large list.

A large list can create the emotional impression of a coordinated pattern.

But quantity does not establish causation.

This is similar to the structure examined in the previous article about alleged deaths connected to the Strategic Defense Initiative.

First, a common category is chosen.

Then people who fit that broad category are collected.

Different circumstances are compressed into one label.

Finally, the length of the list is presented as the strength of the causal connection.

A list can generate questions.

It cannot, by itself, prove that the cases are connected.

Can Silence Become Evidence?

When a person with a classified career disappears, the public naturally imagines inaccessible information.

When investigators withhold sensitive details, silence is given meaning.

When family members reject speculation, some interpret the denial as evidence of pressure.

When no trace is found, the absence itself becomes proof that evidence was removed.

This creates a structure in which every outcome supports the same theory.

If information is released, it is described as a controlled leak.

If information is withheld, it is concealment.

If officials deny the theory, the denial is treated as proof that they must deny it.

If evidence is absent, the case must have been important enough for the evidence to be erased.

Once a theory works this way, it cannot be disproved.

The questions must therefore change.

Is there verifiable evidence directly connecting his disappearance to UFO information?

Is there a documented bridge between his former work and the events of February 27?

Has Wright-Patterson’s mythology predetermined how the disappearance is interpreted?

Are statements from investigators and family members being ignored because they do not fit the story?

Without those checks, a missing person can be transformed into an urban-legend character while the real search is still continuing.

Five Layers of the McCasland Case

The case can be read in five distinct layers.

The first is the confirmed missing-person investigation.

McCasland disappeared from the area of his Albuquerque residence on February 27, 2026, and the search remains active in the public information used for this article.

The second is his confirmed career.

He was an astronautical engineer and retired major general whose assignments involved space research, reconnaissance, acquisition, special programs, and AFRL.

The third is Wright-Patterson’s confirmed UFO history.

Air Force organizations at the base conducted Project Sign, Project Grudge, and Project Blue Book.

The fourth is the limited association described by his family.

After retirement, he briefly advised activities connected to UFO-themed fiction and media on military and technical realism.

The fifth is the urban-legend connection.

He knew about extraterrestrial bodies.

He was abducted to protect classified technology.

An anti-disclosure organization removed him.

His disappearance was connected to unrelated deaths and disappearances involving other researchers.

Parts of the first four layers can be supported by public information.

The fifth layer has not been established by publicly confirmed evidence.

When all five are merged, they form an extremely powerful story.

That is why they must be kept separate.

Conclusion — The Missing Man and the Boundary That Must Not Disappear

William Neil McCasland remains missing as of the information available when this article was prepared.

This is first and foremost a real case involving a real person whose family and investigators seek answers.

Then Wright-Patterson’s UFO history entered the story.

Project Blue Book.

Roswell.

Hangar 18.

Classified research.

Advanced space technology.

A brief connection to the UFO community.

Together, those elements transformed the disappearance into a modern urban legend.

But a base’s mythology does not explain why a person disappeared.

Past access to classified information does not establish causation.

An unresolved case does not make an extraordinary explanation correct.

The boundary that must be protected is not only the boundary around state secrets.

It is the boundary between confirmed facts and imagined narratives.

Between a missing individual and the story constructed around him.

Between information that has not been discovered and information that has deliberately been concealed.

Wright-Patterson became known as a “holy ground” of UFO secrecy not because public records confirmed extraterrestrial bodies there, but because genuine investigations, classified military research, unresolved reports, and Roswell lore accumulated around the same institution.

When a person connected to that institution disappeared, older stories were used to fill the new absence.

What did McCasland know?

Why did he leave his home?

Did his former work have any connection to his disappearance?

The public information available at this time does not permit those questions to be answered.

That is why the case must not be reduced to an urban legend.

The real search and the verifiable record must remain visible.

That is the minimum responsibility owed to a person whose voice is currently absent.

In the next file, we will examine urban legends involving people connected to the Apollo program.

What role has the public assigned to those who traveled closest to the Moon?

And why have their words and silences been interpreted as evidence of lunar secrecy?

Next time—another fragment of truth we will trace together.
I will return to continue the telling.
