RE: the F-15C had the control rods reversed. Same size connections but they were color coded...too bad you can't see into that section of the wing when doing the work by hand. The AF crucified the MX guys...separate tragic story ending in suicide. The pilot "stirred the pot" but never really checked the controls. Pilot morted.
Years ago, my 78-year-old CFI taught me "thumb's up, tab's up" and I used that whether I was flying a Cessna, the Tweet, KC-10, or anything else. That said, I'm not sure I'd have done it after the first takeoff of the day unless MX had been done during the ground time.
I could possibly see myself doing something like that if it was a common technique in the community. Although I hope I would use another technique a really old crusty guy taught me: if you ever do anything to make a plane non-flyable, put a flight glove over the yoke horn (or stick).
Even a dumbass like me will look at it and go "now why the did I put that there?"
A toast...and my heart breaks that we have more -1 ink written in blood.
