I remember one 744 shutting down an engine across the Atlantic and after exiting the track, descending and subsequently being cleared to rejoin the track at a lower level, a voice piped up on 123.45 and said “hey Speedbird, how come after losing an engine you’re still higher than us and faster than us?”, to which the response was “we’ve still got one more engine than you!”
Like I said, an amazing machine.
