>>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.
