UFOs do exist, according to the former head of a secret US government programme who said the presence of alien craft on Earth has been proved “beyond reasonable doubt.”
Luis Elizondo says during his time running the Advanced Aviation Threat Identification Program for the US government he became convinced of the existence of alien craft.
He told the Telegraph newspaper: "In my opinion, if this was a court of law, we have reached the point of 'beyond reasonable doubt'. I hate to use the term UFO but that's what were looking at.
"I think it's pretty clear this is not us, and it's not anyone else, so one has to ask the question where they're from."
A number of details about the project remain classified but Mr Elizondo revealed that considerable work had gone into the project - sufficient enough to map patterns of behaviour.
He said: ”It was enough where we began to see trends and similarities in incidents.
"There were very distinct observeables. Extreme manoeuvrability, hypersonic velocity without a sonic boom, speeds of 7-8,000mph, no flight surfaces on the objects.
“A lot of this is backed with radar signal data, gun camera footage from aircraft, multiple witnesses.
"There was never any display of hostility but the way they manoeuvred, in ways no-one else in the world had, you have to be conscious something could happen.
“We tend to be sceptics by nature. For some of us working on it the time came as an 'Aha!' moment, for others it was a slow progress towards the realisation that these are probably not any type of aircraft in any national inventory.
Debate over UFOs has reached fever pitch after a footage emerged of what some are calling an extraterrestrial craft.
One particular instance details footage from a Navy F/A-18 Super Hornet, a twin-engined fighter, showing an unidentified aircraft surrounded by a glowing aura.
The object travelled at a high speed and rotated as it moved - the pilots onboard are captured as saying “there’s a whole fleet of them”.
Commander David Fravor, a retired US Navy pilot, who was present during the sighting, declared the object was “something not from Earth”.
He added: “As I get closer, as my nose is starting to pull back up, it accelerates and it’s gone.
“Faster than I’d ever seen anything in my life. We turn around, say let’s go see what’s in the water and there’s nothing. Just blue water.
Elon Musk’s Space X programme’s launch of its Falcon 9 rocket on early Saturday morning sparked a meltdown on social media as users feared “the end of the world” and the arrival of an alien UFO after an impressive display across the skies of California.
