This explains why there are almost no photographs of the bolide before the moment of its explosion. An exception to this was one resident of Chelyabinsk, Marat Akhmetvaleyev, who was standing with a camera on the bank of the Miass

Why the stone exploded,eteorite research indicate that the abrupt increase in energy release at altitudes between 45–25 km (kinetic explosion) was not the reason, but the consequence of its destruction. The destruction occurred because of mechanical stresses in the meteoroid, created by the air pressure and the reduction
