[meteorite-list] Fw: Re: - "witness" to July 6 Fireball PA

[Chris Peterson]

A strewn field can be at any orientation with respect to the original meteor 
path, and can lie some miles from the terminal explosion location, depending 
on the height of the explosion and the winds. It is very difficult to 
determine where meteorites will land, even with accurate video records and 
good weather data (from a weather balloon). At best, you can narrow it down 
to a few tens of square miles. After that, it's back to the tried and true: 
interviewing people on the ground, and searching.

Also, it shouldn't be overlooked that a large fireball, even with a terminal 
explosion, is very likely to produce no meteorites at all. Better camera 
data can help access the likelihood of that by helping to narrow down the 
entry angle and velocity.
