Hello List,

I'm working on new page of my website. This page
concerns fireball explosions.

Just some questions:
When a fireball explodes and creates a sonic (shock)
wave observed at seismic stations ++++ can we suppose
that meteorites can be found on the ground?

At which altitude does a normal bolide "explode", or
produce an audible sonic boom?

I'm looking for  "witness map" showing a bolide path,
and witness position with all observations (trajectory
and noise). 

Thank you and best regards, 
Vincent JACQUES
