Yes Capt Eric moody glided the 747 for 29 minutes from memory and some of that time was with the speed brakes deployed in a steeper than required dive due to the first officers oxygen mask falling apart, requiring him to get down fast !
The DC10 Chigaco incident was survivable (read report from NTSB) but the training given for one engine out stated a climb speed which the pilots stuck to, instead of lowering the nose when the left wing lost lift due to the damage/retraction of the slats etc. That was a great shame and I must state the pilots werent at fault, they did the best with what they thought they had.
The United 747 shut down engines 3 and 4, had a huge hole in the fuselage, control surface problems etc but was ladned successfully, but I'm sure it was only just.
Evergreen had an engine fall off on a 747 too and just made it back to the airport.
And there was a cargo707 that had both 3 and 4 fall off, wing on fire and it used its altitude and a little known airport and just made it in, great team work got those guys home.
The Amsterdam 747 had litle or no hope, it didnt have anything in its favour, it had massive control problems, two engines missing, no altitude and heavy.
