A former US Air Force fighter pilot has come forward with claims suggesting there may be substantial documentation supporting one of the most notorious UFO incidents of recent decades.

During a press conference in Washington on Tuesday, Colonel Fred Claussen, a two-time recipient of the Distinguished Flying Cross, disclosed potential sources who might possess knowledge about a 1996 event near Varginha, Brazil.

The incident reportedly commenced on January 13, 1996, when locals witnessed what they described as a UFO crashing in a field near Varginha. Following this, there were numerous reports of peculiar beings, characterized by their bipedal movement, oily brown skin, and prominent red eyes.

Notably, three young women alleged they encountered one of these beings hiding behind a wall close to the crash site.

Although it was reported that Brazilian authorities apprehended at least two of these extraterrestrial beings, it is claimed that the US Air Force seized all related debris, including the bodies and any survivors, initiating a cover-up that has persisted for the past 30 years.

To this date, the US military has said there has never been any physical evidence recovered which proves the existence of UFOs or alien life and have not confirmed that this recovery ever took place.

However, Claussen spoke at an event at the National Press Club organized by investigative filmmaker James Fox, which gathered witnesses and other experts to expose what they claim has been buried about the Varginha crash.

‘If true, I am certain that 30 to 40 Americans had direct knowledge of this flight and its purpose,’ Claussen said.

Often called the ‘Brazilian Roswell,’ Claussen said that even secret missions involve multiple military personnel and various orders that create documented evidence of their existence.

The decorated Air Force veteran explained that if the US military did launch a UFO recovery mission to Brazil, it would have started within Air Mobility Command at Scott Air Force Base in Illinois. 

They would have received the initial order to send a cargo plane, so senior officers there would have known the Varginha crash existed.

‘An international flight plan to Brazil is required even if the mission is classified. Paper trail,’ Claussen declared.

From there, a specific Air Mobility Wing at Charleston Air Force Base in South Carolina would have received a detailed mission order, selected a crew, and prepared a C-17 aircraft for launch – involving dozens of people.

Pilots, loadmasters, schedulers, and commanders at that base would have been in the loop in 1996, and Claussen was convinced the proof of that UFO crash still exists.

Along with the witnesses from Brazil and other UFO researchers, Claussen then challenged the Air Force personnel who allegedly flew to Brazil to become whistleblowers and expose what really happened in 1996.

‘We know this mission happened, and you know it, too. Come forward. The time is now,’ the former pilot said.

The incident 30 years ago played out over several days and also involved the death of a Brazilian police office who was allegedly contaminated by one of the aliens.

On January 13, 1996, witnesses in Varginha spotted a cigar-shaped UFO that looked damaged and had white smoke pouring out of it.

The supposed spacecraft crashed on a farm outside the city, where witness Carlos de Souza, who attended Tuesday’s press conference, found scattered debris and a strange, lightweight metal that reshaped itself after being crumpled.

However, soldiers quickly arrived and de Souza claimed he was ordered to leave at gunpoint. Later, two mysterious men in suits allegedly threatened him at a gas station to stay silent about what he saw.

‘You saw nothing. You know nothing. Or you will have problems for the rest of your life,’ de Souza recounted about his meeting with the unidentified men.

Days later, on January 20, the three young women encountered a reportedly scared, non-human being in a vacant lot that had a strong ammonia smell.

Brazilian military and police captured at least two of these beings that same day, including one grabbed bare-handed by officer Marco Eli Chereze, whose skin was scratched during the capture.

Chereze developed a deadly infection from the alleged scratch and died weeks later.

Dr Armando Monteiro, a forensic pathologist who performed the autopsy on Chereze, revealed during the press conference that he discovered a rare, aggressive bacterium that doctors suspected might have been of alien origin in the officer’s wound.

Soon after, the beings and debris were reportedly transported to a Brazilian airport, where the secret C-17 cargo plane allegedly loaded them and flew back to America.

Although witnesses have maintained that everything they saw was real, no evidence from the reported crash site has been seen again and the death of Chereze was reportedly listed as an infection due to the Earth bacteria strain Staphylococcus schleiferi.
