[meteorite-list] Rock on the ground or not?

[Lasse Lindh]

Chris,  I honestly do not know if there were a sonic boom. I've heard 
sonic booms from aircrafts and those are pretty much loder than from a 
small rock. The background noise level here is other than that of a 
quiet countryside. Two highways and  a major airport (Copenhagen) just a 
fe tens of kilometers away. There are allways rumbling in the air... ;)  
I don't think anyone could hear a sonic boom from here unless it was a 
really big fireball.

There might had been a sonic boom, but I did not hear it.

Regards

Lasse
