YouTube Description

as posted by the channel

At least 11 scientists with ties to nuclear research, NASA, aerospace programs and classified government projects have reportedly vanished or died in mysterious circumstances.

Tom Swarbrick hears from reporter Jon Raasch, as the FBI, Pentagon and NASA open probes into the concerning trend.

Most of the individuals held top security clearance, with access to classified information on space missions, nuclear technology and defence projects.

"The Committee on Oversight and Government Reform is investigating recent unconfirmed public reporting on the disappearance and death of individuals with access to sensitive US scientific information," Republican chairman James Comer wrote in letters sent on Monday.

"These reports allege that at least ten individuals who 'had a connection to US nuclear secrets or rocket technology,' have 'died or mysteriously vanished in recent years.'

"If the reports are accurate, these deaths and disappearances may represent a grave threat to US national security and to US personnel with access to scientific secrets."

Mr Comer noted the "possible sinister connection between a string of mysterious deaths and disappearances which began in 2023."

Missing:

Steven Garcia, government contractor at campus building parts of nuclear weapons

Melissa Casias, adminsitative assistant at nuclear research lab

Anthony Chavez, former employee at nuclear research lab

William Neil McCasland, oversaw funding and research at nuclear lab, retired Air Force General

Dead:

Frank Maiwalk, top scientist detecting signs of alien life

Car Grillmair, scientist working on infrared telescopes, looking at planets with possible water

Michael David Hicks, NASA research scientist

Nuno Loureiro, Nuclear fusion researcher

Jason Thomas, pharmaceutical researcher

Amy Catherine Eskridge, anti-gravity researcher

President Donald Trump was briefed on the disappearances last week.

"Well, I hope it is random, but we are going to know in the next week and a half," Trump said when asked about the missing scientists on Thursday.

"I just left a meeting on that subject, so pretty serious stuff. Hopefully, coincidence... but some of them were very important people, and we are going to look at it."

It was announced last week that Trump's administration and the FBI are looking into the missing scientists.
