London, May 28 (ANI): A Russian scientist claims that a UFO deliberately crashed itself into Tunguska meteor to save Earth from destruction 100 years ago.
Dr Yuri Labvin, president of the Tunguska Spatial Phenomenon Foundation, insists that an alien spacecraft sacrificed itself to prevent the gigantic meteor from crashing into the Earth, above Siberia on June 30,1908.
He said the clash resulted in what is presently known as Tunguska event - a massive blast estimated at 15 megatons that destroyed 80million trees over nearly 100 square miles, however, no one was killed.
Labvin believes that quartz slabs with strange markings found at the site are leftovers of an alien control panel, which fell to the ground after the UFO crashed into the giant rock.
"We don't have any technologies that can print such kind of drawings on crystals," the Sun quoted Labvin as saying.
"We also found ferrum silicate that cannot be produced anywhere, except in space," he added.
"The Tunguska explosion is one of the world's greatest mysteries," Brit UFO expert Nick Pope, who headed the Ministry of Defence's UFO investigation team from 1991-1994, said.
"Previous theories suggest it was caused by an impact from a comet, a mini black hole or a piece of anti-matter. This new theory is the strangest yet.
"We need an analysis of the quartz slabs to be able to prove this one way or another," he added. (ANI)
