Hi Alan

L/A = Leading Airman
N/A = Naval Airman
AB as you say

No, one can't assume FAA Lieutenants were the pilots - in most crews a Lieutenant - if there was one - would be the observer, similar to the make up of Luftwaffe and Kriegsmarine crews. Often in the FAA and RAF the pilot would be an NCO (Petty Officer/Sgt) with one or more officers in his crew - but the pilot would always be in command of the aircraft. I don't think this applied with the Lw. I may be wrong however.
