[meteorite-list] Fireball question / sonic boom

[wahlperry at aol.com]

Hi Jeff and List

Thanks for the link "Sounds Associated with Witnessed Meteorite Falls". 
  As a newcomer to chasing fireballs my experience is limited. My only  
reference is what locals experienced at  Buzzard Coulee , Ash Creek and 
Mifflin. At Buzzard Coulee the locals within the main strewn field 
explained the event as explosions of large fireworks. One resident was 
working in his garage said it sounded like someone  was rolling bowling 
balls across his tin roof than a large flash illuminated outside. Ash 
Creek residents under  one of the main breakups reported hearing a 
large explosion and then seeing a smoke trail followed by two more 
explosions.  At Mifflin I had a chance to talk with numerous residents. 
Near Mineral Point one person described the sound as a large explosion 
followed by a popping sound and then a vacuum sound as the meteor 
passed overhead. At the far end of the strewn field 10 miles East of 
Mineral Point  the sound was described as rumbling sound compared to 
thunder followed by the same vacuum sound as the meteor passed 
overhead. The best way they explained the vacuum sound was as if a 
military jet was passing directly overhead at high speed.

Hi Sonny & all,Everyone has raised some interesting points so far. I 
remember doing a bit of study on this a number of years ago and one 
thing I found that stood out was that in all the situations I looked 
at, when meteorites were found they were ALL within 50km of where a 
sonic boom was heard. Most less than ~25km. I don't know how true that 
is and if it works in every case but for the dozen or so I looked at, 
that was the case.Some may also find my "Sounds Associated with 
Witnessed Meteorite Falls" page interesting. This list was put together 
by Bernd several years ago. Thanks again Bernd!
