So the US Army started to get into flying and they used Air Force uniforms. The person I got this from was a WWII vet and he flew bombers for the Air Force. At some point in the 1950s he switched to the Army. He flew Army Mohawk aircraft and uniform shows one.
On the collar--Major rank and Trans Corp. Name tape and US Army present. On left leg you see an attachment---that is a clip covered in cloth. Was used in flight to hold checklist, etc.
