Re: (meteorobs) Fireball sonic booms!
Hello Bob:
Thanks for your email and references about the V2. A sonic boom was not
heard at the impact site as the V2 hit before the delayed sonic boom
arrived. It is possible that a boom was heard down range along the
trajectory some distance away from the impact point. This V2 thing was just
a diversion. I am more interested in when sonic booms were recognized to be
associated with an entering meteoroid. None of the papers I have mention
this.
Cheers:
Ed
