Actually, most meteorites tend to stay in one piece upon impact (provided
its under a certian size). Therefore, I suspect that "bolide" still
doesn't really apply to meteorites.=20
FYI, comets are usually associated with exploding; in fact, exploding
seems to be far more common than impacting. This phenomenon has been
observed many times during human history (the Siberian impact, for
example), where a comet has been seen aproaching the ground, and exploding
above the ground. Because of this, comet "impacts" rarely leave a crater.
