Not really - it can take off with one out of four engines working...
Not that I care to be on it...
“How far can we go on one engine?”
“All the way to the scene of the crash, I am sure. And we will beat the emergency vehicles by twenty minutes, at my guess...”
It landed safely, BTW. Duh.
A Boeing 747 is designed to glide if all 4 engines fail. If this happens at 38,000 feet the plane will glide for 120 miles - losing altitude all the time - before landing (or crashing!).
