Message: 1942 was the year the 90th Bomb Group was created. Look close at the patch. Under the skull are "crossed bombs" instead of the crossed bones that the pirates had. The patch with the 5 is the 5th Airforce patch. The other patch you describe Sounds like the 8th Airforce Patch. Do the Wings look like they come out of the number 8? Go to this link:
http://www.b24bestweb.com/Patches-090-308.htmSee if the patch you describe is there. Did your dad continue in the military? The 90th BG only lasted from 1942-1945. If he continued in the Airforce he may have gone to the 8th Airforce after his tour with the 90th in the 5th Airforce.
