Ablation ceases at 3-4 km/s (about Mach 10), and this is about where the
meteoroid becomes invisible. For a typical meteorite, it will rapidly lose
this remaining velocity and enter nearly vertical dark flight.

It seems like there have been many fireball sightings in the past few
months but no material being found on the ground, as in the recent
Oklahoma event. I was wondering if the absence of a sonic boom has
anything to do with it.

Curious... I know there are many variables involved, and it probably
varies with the conditions under which each event occurs, but I've read
that some people have heard sonic booms (as low boom/rumbles) up to 50
miles
Thanks for the replies. It sounds like a sonic boom my be a determining
factor in recovering meteorites and which fireballs to chase.
Yep...that's what I've been saying for yearsIf no booms...save
yourself the wear and tear.

There are several falls where no sonic boom was noticed. Speaking of US
falls,
the last two that come to mind are Berthoud, CO and New Orleans, LA.
Others
that I can readily recall are Salem, OR and Athens, AL. Reports from the
latter
two specifically state there were no explosions

Thanks Frank...never knew there were any sizable
meteorites recovered from
falls without any sonic booms reported. I bet there were
some for those
above, but there probably weren't people
or ... if a meteor produces a sonic boom, but nobody is there to hear it, does
it still drop meteorites? ;^)

Something to consider... If all events with sonic booms generate meteorites,
then there are meteorites on the ground in Louisiana/Mississippi from the big
fireball there a couple of months back. Here's Jake Schaefer's page on that
event again...

I believe its in the neighborhood of 7,000 mph. If its a small meteoroid,
it will extinguish way too high
