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.
