PRIBRAM - Fell April 7, 1959 - first recovered meteorite with a known
orbit - 19 fragments found, largest 4.3 kg - total 9.5 kg recovered.
                        I read somewhere that some fragments were found prior to the
trajectory and orbital calculations. Can anyone confirm this with a
reference?

LOST CITY - First triangulated meteor photographed by the Prairie
Network in the U.S.A. Fell 3 Jan 1970 and found 9 Jan 1970. Total
wt. 17kg.
                     - I read somewhere that other fragments from this fall have
since been recovered. Can anyone confirm this with a reference?

INNISFREE - Fell 5 Feb 1977 - Photographed by the Canadian MORP
Fireball Network - 11 days later a 2.07 kg sample was found a
                            few hundred meters from the predicted
computer projection. 8 other fragments have since been found, Total
mass 3.79 kg.
                        

Sadly both the Prairie Network in the U.S.A. and the MORP Network in
Canada was shut down because of funding issues. The Sandia Research
Group has since distributed two different all-sky cameras forming a
video patrol network across much of North America. Some others have
set up their own all-sky patrol cameras. The first Sandia cameras
were of the hub-cap or convex mirror type but there was a problem
reducing start and end points of a fireball with this type of
system. They have since replaced most of these units with fisheye
lens systems which are better. The first two systems used vcr's for
recording but this has now been upgraded to video capture of a moving
object to a computer hard drive. No more long hours wasted searching
vcr tapes.
