Đo, hvala na linku - ako ste ga propustili u komentarima na prethodni post, evo dokumentarca:

"The Tunguska event, or Tunguska blast or Tunguska explosion, was an enormously powerful explosion that occurred near the Podkamennaya Tunguska River in what is now Krasnoyarsk Krai, Russia, at about 7:14 a.m. KRAT (0:14 UT) on June 30 [O.S. June 17, 1908. The explosion is believed to have been caused by the air burst of a large meteoroid or comet fragment at an altitude of 5--10 kilometres (3--6 mi) above the Earth's surface. Different studies have yielded varying estimates of the object's size, with general agreement that it was a few tens of metres across."
