Alex, I assume you have seen MACR 6303 for the loss of Walsh. It start here for those with fold3 access. No real infomation other than Walsh bailed out after the plane hit some prop wash during the bomb run. The pilot was Benjamin F Crawford, 762nd BS.

This was produced by Benjamin F Crawford. His plane was apparently White M, i.e. "White Mike"", serial number ??.
MACR 9044 for Olson and Ebe (pilot Logan) starts here:
