Mantle, a former director of investigations for the British UFO Research Association, told The Sun: "There are some of our colleagues that believe that Russia has alien technology from this event, but as yet they have not been able to understand it - just like their counterparts in Roswell in 1947.".
Now, 39 years later, Brit investigator Philip Mantle has dubbed the incident "The Russian Roswell" - after the famous UFO crash in the New Mexico desert, USA, in 1947.
The strike - dubbed "Russia's Roswell Incident" after the famous 1947 New Mexico UFO - was set upon by Soviet scientists, who made some remarkable discoveries.
THE Roswell Incident is a famous case in America which, some people believe, involved an alien UFO crash landing and a cover-up by the US government.
Mikhail Gershtein, Russia’s top UFO researcher, said lots of witnesses compared the fire burning at the site to electrical welding.
