A-320 Ditch PB
I realize the odds are long of this happening, but the people who talk of these long odds, primarily engineers, are always proven wrong, e.g. UAL Siox City Iowa USA, Us Air A-330 deadsticks with O fuel into Azores. The WTC was designed to take a direcect hit from a B-707 going transcon, but far lighter A/C 757 and 767 going transcon took the WTC down, the 75 and 76 I know had way less fuel on board and a B-707 was a better weapon because it was a heavy metal machine.
Multiple emergencies or something unexpected would keep pilots minds out of the box for these improbable expectations. Checklists! maybe, maybe not, if you waste time on a checklist for the wrong thing you'll be just another meaningless statistic. Swiss Air ASKS for a fuel dump sight! At that point I own the entire Fing sky and tell ATC. What I am getting at is pilots need to be put in these situations occassionally, then need to tell ATC I own all airspace 0-370 the ac is uncontrollable block it for me know. Read the Alaska Airlines NTSB report. That's the MD-80 that crashed off Lax. I might have died but it would have been heading for Edwards AFB and I would have told Lax center block all altitudes vector us to Edwards. If you read the report the company was blasaie about the whole thing because the C/O was to cool in his radio transmissions and behaving like a test pilot with the flaps. Alaska Mtx was mainly to blame but what was this guy thinkinking? Read the report.
Another interesting thing on an A-320 is a low speed abort, say between 50-72 kts I asked for one. Counter intuitive...but you are in no mans land litte rudder and little or no nws, we kept it on the runway but this isn't std training on the AB-320. This kind of abort is highly possible. Give it a try sometime in the sim 10 kts crosswind and maybe an engine failure. Interesting.
