I am researching an airman who actually joined the RAF in 1937. He reached the rank of Corporal and was an Air Mechanic/Fitter during the War. Family information is that he flew operational missions for several months and we have his Aircrew Europe Star, 1939-45 Star Italy Star, War Medal and Defence Medal. His service record also shows that in 1944 he was posted to 1FTLU, which I believe is 1 French Technical Liaison Unit?

Is anyone able to tell me :
a) Whether a Corporal Air mechanic would ever have flown operationally in order to qualify for his Aircrew Europe Star and
b) What a FTLU was and what his role within such a unit would have been?
