The video has caused a stir among 'experts' who have drawn similarities between it and a notorious UFO sighting in 1980 that had been shrouded in secrecy This "amazing" footage shows a diamond-shaped UFO which was spotted from inside a plane, as it flew 43,000ft above Texas in the USA. The video has caused a stir among 'experts' who have drawn similarities between it and a notorious UFO sighting in 1980 that had been shrouded in secrecy. This new clip was recorded by a man, identified only as Steve, who works as a director of aircraft maintenance for a corporate jet fleet in the USA. He sent the footage to SecureTeam10, a group of UFO experts, who analyse the footage and share their findings online. Tyler from SecureTeam said: "It was unbeknown to anybody at the time, but afterwards it was realised that this odd-diamond shaped UFO looks eerily similar to the UFO seen in one of the top ten most notorious and well researched UFO sightings known in the entire world."
