It's difficult to know where to start. Having stalled many times, admittedly not in heavy jets, I've never know a stall cause engine failure. My guess the journo has read somewhere about engine stalls, and thinks they're the same thing. Or perhaps cars "stalling", when the engine does stop. Doh! Air France 447 wasn't a stall the pilots couldn't recover from; it was a stall, the pilots DIDN'T recover from.
