FYI.the book about the Gimli glider is a good read, and the movie is excellent as well..
I can imagine the “butt-pucker factor” on the Gimli Glider was quite high.
I have been on a 747 with an engine loss, dumping fuel routine and fire trucks following you down the runway.
A 747 with an engine loss is a butt-pucker factor of zero compared to the Gimli incident.
