FedEx’s engineers do not have an easy job, but that does not mean they do not have fun with it. In between flights, FedEx pilots fill out a gripe sheet, that tells mechanics and engineers what problems and concerns they encountered while flying said aircraft.

Except for the times they do not do any repairs. Sometimes some of those entries just don’t warrant the gravity they usually do, and when the mechanics feel like it, they do some crazy things. Check this out.
