To be clear, in meteoritics "falls" are meteorites where either the 
meteorite fall itself is witnessed, or the preceding fireball is 
witnessed. "Finds" are meteorites where the fall was unwitnessed. 
Meteors cannot be either, although a meteor sighting may contribute to a 
meteorite being classified as a fall. Falls are rare, and instrumentally 
recorded ones rarer still.

We regularly analyze multistation events with our Colorado cameras in 
order to determine both the atmospheric path and original orbit of 
meteoroids (you can even do simple online azimuth triangulation yourself 
using our data). Many meteors have had mass, velocity, and angle 
characteristics suggesting the possibility of meteorite formation, but 
after six years none have been recovered. Even knowing the meteor path 
with absolute accuracy is not enough to make recoveries easy. In fact, 
finding a meteorite from camera data is an extremely difficult problem- 
there are large uncertainties that cannot ever be eliminated.
