There was a test flight around the 70s that intentionally brought a large airliner jet (don't remember exact model) to near Mach 1 in a descent. They couldn't trim nose up so they had to move the stick forward, and then they were able to trim nose up. Don't know if they tried using the trim wheel with their hands.
A major crash occurred near Montreal when a DC8, after takeoff, pitched up, then stalled, and crashed. It was blamed on trim switch. DC 8s were known at the time to have switch problems. I believe they didn't have a recorder. This was in 1963.
