"Meteorite of Thunguska" or "Tunguskiy Meteorit" is remains unknown event, same as "Did really Tesla sent an electricity charge to the moon and its reflected it ?", there comes " why moon didn't explode then ?", its not a big peace of mirror, and its not made of metal, anyways even if it was work of Tesla's experiments, still it doesn't means that we should stop trying, otherwise we couldn't have created many cures for many sicknesses, "sacrifice is a major factor of success" thats what i say, if Tesla hadn't see that big electricity ball flies away from his tower, he wouldn't discover that electricity can fly, and it has purple color. Meteorite of Tunguska could be his hands work, he probably felt right to hit it coz its his folks motherland :XD:
