The short answer is a definite no. While a sonic boom in conjunction
with a fireball sighting is an excellent indicator that meteorites
may have been produced, a single visual report is of no use for
determining where to go looking. Two (typically vague) visual
reports plus coordinates for a dozen geographically spread people
who heard/felt the sonic boom might give you a general area, but
you're probably still talking over 100 square miles. In Arizona,
if you thoroughly searched any desert area of even 5 square miles,
you'd almost certainly find one or more meteorites, so you see how
limited the value is of visual sightings from (usually) untrained
witnesses. --Rob
