When a UFO spotter sent a local news team his film of mysterious spacecraft whizzing above Denver, Colorado, they sent their own cameraman out to prove it was a hoax.
But after a few hours of filming from the exact same spot, the team captured footage that, far from debunking the strange sighting, appears to confirm it.
The city’s Fox-affiliated TV station KDVR have no explanation, even after drafting in an aviation expert in a final bid to disprove the phenomenon.
But after reviewing the footage, Steve Cowell told the team: ‘That is not an airplane, that is not a helicopter, those are not birds, I can’t identify it.’
The original video, sent by a man who refused to be identified, seems to show a series of dark objects flying at high speed in and out of clouds.
