Twin-engine turbine powered commercial aeroplanes have an "in-flight

FWIW, in the past, I worked on a C-135 that had provisions for 6

What are the chances of one engine going out in a 747 during

Depends


I'm not talking about an engine falling off the jet, but just stop
working. Also, what are the chances of two, three, and four engines
going out? What about the two jet engines on a 777?



Remote.
