I have in front of me my Student Pilot Licence n. 73XX94 issued on 31 March 1966
D120A,
"Aeroplanes, balloons and airships."
Mine was issued six months later but I don't have it any more. Can you refresh my memory about the wonderful language inside the cover, requesting help for the holder, if necessary. I vaguely remember something about "...commands and requires civil and military authorities..."
