A baffling mystery is unfolding in New Mexico after a retired United States Air Force general vanished without a trace.

Maj Gen William Neil McCasland, a respected military engineer with decades of experience in advanced defence research, walked out of his Albuquerque home on 27 February and has not been seen since.

The Day the General Walked Out and Disappeared

According to local authorities, McCasland left his home on Quail Run Court at around 11:00am on 27 February. He walked away without his mobile phone and without a watch. Family members reported him missing shortly afterwards when he failed to return.

The Bernalillo County Sheriff's Office issued a Silver Alert as search efforts quickly intensified. Federal authorities later joined the investigation and the FBI is now assisting local law enforcement.

Search teams have canvassed more than 600 homes in the surrounding neighbourhood. Officers have also reviewed security footage and questioned residents across the area. Despite the extensive search effort, there have been no confirmed sightings of the retired general.

Twelve days after he vanished, the case remains unsolved and investigators say there is still no clear explanation for where he might have gone.

Strange UFO X Account That Went Silent

The mystery deepened when researchers began examining a verified X account known as '@TMBSPACESHIPS.' The account, which used the display name 'Electric Propulsive Spacecraft,' has been posting technical commentary about exotic propulsion systems since late 2022.

Over the past few years the account shared more than 1,600 posts discussing plasma physics, ionised gas propulsion and experimental spacecraft technologies. Its bio described the author as a '38 year Active Duty USAF PhD Engineer' with experience connected to Air Force research institutions.

What immediately caught attention was the timing of its final post. The account stopped posting on 27 February. That was the same day McCasland walked out of his home and disappeared.

The last message from the account was published roughly thirty minutes before the retired general was last seen.

Researchers quickly noticed similarities between the technical topics discussed by the account and McCasland's professional background, which included work in directed energy research, pulsed power systems and advanced aerospace technologies.

UFO Schematic Sparking Fresh Questions

Interest in the account intensified after investigators revisited an unusual post shared in December 2023. The message included a photograph of a hand drawn diagram on notebook paper.

The author claimed the drawing represented something seen in the sky in 1998 while flying aboard a KC 135 refuelling aircraft.

The diagram showed a glowing object descending through the atmosphere in sharp steps while leaving a long multicoloured trail behind it. Notes written beside the drawing referenced plasma emissions, ionised helium and a phenomenon known in laboratory physics as 'Crookes dark space.'

Experts analysing the post later enhanced the image and discovered faint text from the opposite side of the page. What appeared beneath the drawing was not simple notes but what looked like an engineering component list.

The list included items such as an electron gun, magnetic compressor, tungsten filament and a continuous Marx generator. These are all pieces of equipment associated with high voltage plasma experiments and particle acceleration systems.

According to analysts who studied the image, the components described on the second page appeared to form a theoretical propulsion system. They argued the list looked like an attempt to reverse engineer the object shown in the original drawing.

McCasland's Career Has Become Part of the Mystery

McCasland's professional background has made the discovery particularly intriguing. During his career he worked within the Air Force Research Laboratory and held roles connected to some of the United States military's most sensitive technological programmes.

At one stage he served as director of special programmes within the Office of the Under Secretary of Defence. That role placed him close to the oversight process for highly classified defence research projects.

People familiar with the case say his expertise in directed energy systems, pulsed power technology and advanced aerospace concepts overlaps with the technical themes discussed on the mysterious X account.

Some researchers believe the account may have deliberately obscured its owner's identity. The profile listed incorrect universities and slightly inaccurate career details. Analysts say this could have been done intentionally to avoid simple identification while still signalling credibility to those familiar with the field.

For now investigators have not confirmed any direct link between the account and the missing general. However the unusual timing has left both authorities and online observers searching for answers.

As the search for McCasland continues, the strange silence of the UFO themed account has only deepened one of the most unusual disappearance cases in recent memory.
