Top Space Researcher Says The UFO That Chased US Jets May Be Aliens • Latest UFO sightings A top scientist bared his thought recently about a video footage that made the rounds online showing a UFO apparently chasing US jet fighters. Dr Michio Kaku has said the mysterious object that the US military personnel reported could be a new type of super-fast aircraft. The US military personnel reported seeing a strange object that apparently chased some of their warplanes. However, the well-known physicist also said that the UFO could be extraterrestrials. Reports that the Pentagon has been running a multi-million-pound program dedicated to investigating UFOs for years has emerged recently. A video has also been released depicting two US pilots checking on unusual aircraft in the Pacific Ocean approximately a hundred miles from San Diego. The UFO reportedly first made an appearance at 80,000 feet. Strangely enough, it hurtled towards the sea before halting at around 20,000ft and then vanishing. Dr Kaku, the world-renowned physicist, gave his thoughts on the reported encounter and Pentagon research. He said that UFOs chasing the military jets might be experimental hypersonic drones, or perhaps aliens from outer space. He added that he keeps an open mind. Both China and Russia are developing hypersonic aircraft with speed reportedly over five times the speed of sound. China has been sending drones into space in recent years and experimenting with hypersonic technology. There were reports that the People’s Liberation Army (PLS) has been developing ballistic missiles called hypersonic glide vehicles (HGV), which can strike anywhere in the US in less than an hour. They are capable of delivering nuclear payloads within a matter of minutes, which might leave defence systems useless. Russia has claimed their 16,000mph hypersonic nuke missiles could be all set for operation in two years. The US also has reportedly developing hypersonic weapons that can travel at five times the speed of sound and destroy targets with a kinetic energy warhead. Meanwhile, former US Navy pilot commander David Fravor, who chased a UFO in 2004 in one of the two fighter jets, warned that leaders in the world should take the alien threat seriously. Speaking about his encounter, Mr Fravor said that they saw the UFO on a bright day. He said that it had no windows and no form of propulsion. He described the UFO as a big white object. He cut across to get closer to the UFO, but it accelerated in tremendous speed and disappeared. He said that it was gone in just a matter of a second.
