Concur with
John E - whilst there might be twice the chance of engine failure, there's a significantly higher chance of flyaway following a SINGLE engine failure, which is what we're really talking about. I can't remember
ever reading or hearing about a double concurrent turbine engine failure - & before someone finds one, I mean not caused by severe icing or fuel starvation, neither of which would likely happen with this sort of operation, I'd suggest.
All in all, hats off to the pilot, for a skillful &/or lucky outcome. It's always heartening to see a positive outcome to what could, so easily, have been otherwise.
