Comets are not bombs. It is unlikely that one "exploded." (especially if they are composed of ice, as the conventional wisdom would have it.)

Meteors are not bombs, either, but judging by the Tunguska event of 1908 and the Barringer crater, they explode just fine.

Get anything with mass going fast enough and it will always explode on meeting the denser part of our atmostphere.

I'm wondering what definition of explode you would choose. No one really knows what happened at Tunguska, and Barringer is just an impact crater. When an airplane crashes into the ground and debris is scattered all over the place no one would suggest that an explosion occurred unless the event were accompanied by a rapid combustion of fuel. (oxidation or other exothermic reaction)
