Russian Hard Rock

.....on a meteoric descent: [video]http://www.youtube.com/watch?v=b7mLUIDGqmw[/video] Russia gets all the best meteors. This beats any explosion done in the movies or on Mythbusters. The explosions of smaller meteor fragments after the initial explosion are pretty cool.

really cool police car videos of it below the main video--just no audio of the sonic boom/explosion.

Those aren't necessarily police car videos--many civilians have dashcams in Russia due to a high prevalence of insurance fraud.

These stories are bugging me, though. I'm sure there were sonic booms involved, and a sonic boom can break glass, but there's no way only sonic booms did that much damage--there was a serious pressure wave from that explosion, especially if they were estimating it to have happened above 30km (~95,000 ft.).

Those weren't sonic booms. Those were shockwaves from the main body and fragments exploding. Sonic booms are several, if not many, orders of magnitude less intense.

Just this morning I heard a report that there was also a large fragment that hit the ground, potentially responsible for a blast.

Aside from the explosion, there still had to be sonic booms as the various fragments were traveling at supersonic speeds.

I've heard sonic booms before--my grandparents lived in SD, not far from typical flight paths of B-1Bs coming out of Ellsworth AFB. We would visit for a couple weeks every summer in the '70s and '80s, and I heard a few when jets were still allowed to go supersonic and low over sparsely populated areas.
