Hi Garandshooter,
Joe Baugher mentions that s/n 42-64494 has been "salvaged" on 18. January 1944 - that's pretty different from MIA. The a/c must have had a hard landing (as seen on the photo above) or something similar. But (playing devil's advocate) it is still possible they have repaired the same a/c later
. There is
no accident report for this particular B-24H (check
here), which means
it didn't crash, there is no MACR, no other reports. It could be a typo as well (the correct year of salvaging could be 1945 not 1944). I remember that the 455-th BG. moved to Italy in January-February 1944. Is it possible at all for an a/c from the 742-nd BS to be salvaged on Jan 18. 1944? You probably have the exact time of the group moving from your research.
Checking the above photo from B24bestweb I noticed that the photo credits go to AFHRA. This indicates (for me) that there is a report with the same photo somewhere in the documents of the squadron or the group. I would suggest you contact AFHRA and start searching for the Group- resp. Squadron diaries. This could be a mission report or just a daily report in the diary - who knows. I personally believe that this is the same a/c you are looking for.
