UFOs could have been flying over the US for years
Leading extraterrestrial expert Nick Pope is convinced that the mystery objects shot down recently over US airspace could be only the start of the alien revelations to emerge from the country.
Pope, who ran the UK Government's UFO project for the Ministry of Defence, said that the Pentagon appears comfortable to let the alien speculation run.
He said: "It's interesting that they are almost pushing the alien narrative a little bit."
Pope warned that the authorities would be foolish to underestimate the threat that aliens pose to the planet.
He said: "When you see the thing you think, it's just a balloon. But the balloon is a delivery mechanism.
"The real issue here is, by all accounts this is extremely sophisticated."
