After every flight, UPS pilots fill out a “gripe sheet,” a log where they report any issues with the aircraft. Mechanics then review these notes, fix what needs fixing, and write down how they resolved each problem.
These exchanges between pilots (P) and maintenance crews (S) have become legendary for their quick wit and dry humor. Here are some of the funniest real examples ever recorded:
P: Left inside main tire almost needs replacement.
S: Almost replaced left inside main tire.
P: Test flight OK, except auto-land was very rough.
S: Auto-land not installed on this aircraft.
P: Something loose in the cockpit.
S: Something tightened in the cockpit.
P: Dead bugs on windshield.
S: Live bugs on back order.
P: Autopilot in altitude-hold mode produces a 200 ft per minute descent.
S: Cannot reproduce problem on ground.
P: Evidence of leak on right main landing gear.
S: Evidence removed.
P: DME volume unbelievably loud.
S: DME volume set to a more believable level.
P: Friction locks cause throttle levers to stick.
S: That’s what friction locks are for.
P: IFF inoperative in OFF mode.
S: IFF always inoperative in OFF mode.
P: Suspected crack in windshield.
S: Suspect you’re right.
P: Number 3 engine missing.
S: Engine found on right wing after brief search.
P: Aircraft handles funny.
S: Aircraft told to straighten up, fly right, and behave.
P: Target radar hums.
S: Reprogrammed target radar with lyrics.
P: Mouse in cockpit.
S: Cat installed.
P: Noise coming from under instrument panel—sounds like someone tapping with a hammer.
S: Hammer confiscated from culprit.
It’s clear that UPS mechanics not only keep their planes in top shape—but also keep their sense of humor flying high. ✈️
