Scientific paper

The purpose of this paper is to show that lack of residual meteorites is typical for a fall of a stony or carbonaceous bolide tens of meters in size. A Tunguska-sized body penetrates deep into the atmosphere and is broken into a great deal of fragments the maximum size of which is smaller than 10 cm. Numerical simulations of analogous problems show that the fragments are separated from each other at a stage of dramatic deceleration of the bolide. Computations made here give that 3-10 cm stony fragments fully ablate either inside or outside the fireball due to high radiation flux. Only if the fragments accidentally gain significant lateral velocities at altitudes above 15 km, could their ponderable remnants reach the ground at 5-10 km from the explosion epicenter. Vaporized material of the impactor does not touch the ground and moves upward along the wake.
