The world's top UFO hunter - who never saw a flying saucer in 62 years of research - has died aged 84.
Retired nuclear physicist Stanton Friedman was worshipped by thousands of alien believers across the planet.
He died at Toronto's Pearson International Airport on his way home to Frederiction, Canada, on Monday night after a UFO talk in Columbus, Ohio, his family said.

He was the first civilian investigator to probe the so-called 'Roswell Incident' in 1947 and bring it to the attention of the world.
The incident is seen as the 'holy grail' by Ufologists after the US military is rumoured to have recovered two crashed flying discs and several alien bodies from a ranch in New Mexico.

Since 1967 Mr Friedman lectured on the subject 'Flying Saucers are Real' at more than 700 colleges and over 100 professional groups in all 50 US states, nine Canadian Provinces, 12 cities in England and nine in other countries.
One of his most famous sayings was: 'Don't be an apologist ufologist.'
He also appeared on hundreds of radio and TV shows and won debates at the Oxford University Debating Society.
Mr Friedman received a Lifetime Achievement Award at a UFO conference in Holmfirth, West Yorks, in September 2015, presented by former detective Gary Heseltine, who now edits UFO Truth Magazine.
Mr Heseltine, 59, of Scholes, West Yorks, said: 'He was a man who championed all his life that ET visitations to planet Earth were real despite the fact that he had never had a personal sighting.
'I first met him in Dublin at the first Irish UFO Conference in 2004 and I have to admit that I was in awe to be in his presence for the first time such was his incredible reputation in the field of Ufology worldwide.
'In the summer of 2015, I had the great honour of having him as a speaker at the UFO Truth Magazine International Conference in Holmfirth and I clearly remember picking him up at the airport and thinking how cool it was to have such a great man in the car with me.
