Pilots have cleans hands...
Well, just one thing:
When a crew write down in logbook: "Autopilot u/s"...
Is it that hard to be a little bit more specific: we don't have access to a time travel machine to check out the cockpit in flight! I need info...
But, eh, let be honest: there's good and bad individuals in all trades! Pilots, Grease monkeys, sparkys: we are trying our best to keep these machines flying!
Cheers!
