[meteorite-list] HUGE Meteor Sighting in Cottonwood AZ - Stats from fall

[Chris Peterson]

The majority that produce _falls_, yes, but not _finds_, I think. That 
is, your typical find (either a single individual or several pieces) 
probably didn't come from a spectacular meteor event. Of course, finds 
in large strewn fields are a different matter.

Atmospheric entry models demonstrate that it's not difficult for a small 
body to drop a few rocks on the ground without ever depositing the sort 
of energy into the atmosphere we associate with bright fireballs lasting 
several seconds and producing audible acoustics at ground level.
