Keg worth is worth a good look. The crew incorrectly identified an engine fire, and shut down the good engine. The only remaining engine. Performed ok at flight idle on descent, but was unable to provide sufficient thrust when spin up was required after configured for landing.
AF447 , failed to carry out the UAS check list(on my type is extremely complicated.......... 3 items ....... From memory), and then failed to recognise a stall, .....a deep stall.
Mate not only are you not comparing apples with apples, you are attempting to compare apples with a skungy spat out orange pip!
As for your hero who got a fully laden B747 back on the ground in seconds with a double right hand side engine failure, did he do it single pilot? How did he actually confirm the problem that he actually had, and then work out a course of action in that time. From another era of a man and his dog perhaps?
Kegworth was caused (largely) by rushing to judgement, they would have done a much better job if they had sat on their hands for a little while an examined very closely exactly what the problem was.
