I had another idea, checking the US Navy and USMC casualty lists available at
https://www.naval-history.net/WW2USCas.htm (actually I have compiled them into files to be able to search the whole list) and searched death date of 10 September 1945. While the list is not complete (some names are missing, and a good part of the names have no death date, especially the accidental ones), it can still be useful.
On the USN side, found no transport aircrew missing, just 4 people lost in Philippines in a MIA Avenger (see
https://fr.findagrave.com/memorial/5...harles-holsten for details).
On the USMC side, no air casualty for this date.
The usual way for USN and USMC MIA is to be declared dead one year and one day after they went missing, so missing USN and USMC men lost on 10 September 1945 will be listed on 11 September 1946 by ABMC. This is the case of the four men lost with the Avenger listed above, and there is only one more man listed for this date, so my guess is that no USN/USMC transport crew was lost that day.
