Re: (meteorobs) Comets hit Spain?
Small meteorites and somewhat larger chunks of ice, have a terminal
velocity somewhat below the speed of sound at the Earth's surface. Thus
they have no sonic booms for the part of their path below this critical
speed. They still make a sound as they "swish" through the air.
