Re: [meteorite-list] Fireball question / sonic boom

[GeoZay]

>>George jut brought up a  good point and I have a question. The speed of 
sound is about 760  MPH.

What is the speed at which a meteoroid extinguishes and is no longer  
incandescent?>>

I believe its in the neighborhood of 7,000 mph.  If its a small meteoroid, 
it will extinguish way too high for a sonic boom to  reach the ground.
