Can't find anything on the collision in the copies of the 511FS history I have.
Rickert joined in Aug 44 as a 2nd Lt and became a 1st Lt in Feb 45.
Palmer joined in March 45 and his first mission was on the 12th March 45 in K4-C.
No collision or deaths recorded in March 45 or of a collision 14th Match 45?? Non combat anyway?
Rickert definitely was at the unit in April 45 - claiming 3 ground victories on 16th April.
No more listings for Palmer.
Palmer is buried in the USA
regrds,
Mark
Bit more.
