Not a 1011 mech myself, although I did a bit at Marshalls in the 80's, but one of my favourite stories came from an ex-GF man who was telling me about a Tristar that had just come off heavy maintenance and had been test flown...the general manager was in his office, scribbling away on a sheet of paper;
"Whatcha doin?"
"Filling out the 'boom' sheet."
"Boom sheet?" (abject terror, thinking that someone was about the get the chop for some grave error)
"Yep, the boom sheet." He went on to explain that in the war, when Lockheed were turning out P-38's by the thousand, after each test flight a sheet would be filled out with any defects noted on the test flight, then it was taped onto one of the aircraft's twin tail booms, hence the name; and it had remained in Lockheed terminology ever since!
