The vast majority of meteorites retard while they are still far too high for
sonic booms to reach the ground. The big, impressive fireballs that are more
massive and reach lower heights are the exceptions. The meteoroids that slow
down while still high are more likely to produce single meteorites; those
that have enough mass to reach low altitudes still traveling at high speed
tend to fragment and produce strewn fields.

Subject: Re: [meteorite-list] Fireball question / sonic boom
The
absence of one, however, probably shouldn't be taken as an indicator that
they were not, since a meteor can still end (without complete ablation)
high
enough that no sonic boom will reach the ground.<<
Wouldn't these(meteorites) that are high enuf that no sonic boom will
reach the ground end up being rather small meteorites? This because a
small
meteorite will be slowed down rather quickly higher up. The larger
meteorites
having more momentum to carry it on down to the lower atmosphere will
still
have a velocity fast enuf to produce the big thunder like sonics?
