Had two diversions and one almost.
The first diversion occurred on a L-1011 I was jump seating on (1977??). We were flying from MIA
when we started losing oil from the #2 engine. The crew shut it down and we went to JFK
The second diversion occurred on another L-1011 (1982??) flying from ATL
. Right after take-off the airplane jerked abruptly to the right and we went back to ATL
. The step aside gearbox on the #3 engine failed during the climb out. I was in the cabin on this one.
The almost occurred on a Northwest DC-10-30 from Rome to DTW
in 2002. An idiot had way too much to drink and started being a royal pain. It took a lot of duct tape (honest, I saw it) and 4 very big male passengers to keep him in line and we almost diverted to YUL
A very large police officer can on at DTW
and the idiot left peacefully. There were at least 2 federal charges placed against him.
