Nowadays the situation with so called "Tunguska meteorite" resembles a pendulum: one group of scientists turns up new (and old too) strong evidence that Tunguska couldn't have been an asteroid made of stone or iron, thus it had to be a comet. But pretty soon, another group of scientists comes up with new (and old too) strong arguments that Tunguska could not have been a comet, thus the only way-out is that it must have been an asteroid. These swings hint that both groups are right and wrong at the same time: Tunguska 1908 was neither an asteroid, nor a comet. And indeed, now I try to demonstrate that it could not have been any known spacebody-fall.
