This jogs another thought. There has been a number of multi station
photographic Fireball networks in existence....also some no longer operating
that has detected a number of Fireballs that has dropped recovered
meteorites. From these photographs, the orbits of recovered meteorites has
been determined. Has any of these ever indicated that the objects came from
an area other than the asteroid belt? Has any multi station fireball
photographs where meteorites haven't been recovered and were not part of a
recognized meteor shower been shown to come from anywhere other than the
asteroid belt? If some where detected, roughly what percentage of Asteroidal
origin vs something that could be considered short orbit comet parentage?
