Big difference between ditching during daylight, good visibility, and calm seas vs. night, low visibility, and moderate to rough seas.

Actually, the Kegworth disaster would suggest that changing the flight deck from what the crews are used to might be a bad idea. One of the contributing factors in Kegworth was that on the 737-400...

Plus Sully got the APU running so he had full electrical power and all the instrumentation that goes with it.
Still haven't heard confirmation one way or the other, but if both engines went...

Based on that amount of damage, they must have hit the water HARD!
That wasn't a Sully style gentle ditching... The pilots were lucky to get out.

I rather doubt a 737-200 is going to have a DFDR. More likely one of the old analog tape units - and impact loads/ROD are not likely...

As for the fuselage breaking into three pieces - sorry but...

PigBoat87

If you take a look at the Extended Range operations rules (aka ETOPS) for 3 and 4 engine aircraft, you would have seen that years ago. In short, freight operators are basically exempt...

BFSGrad

Depends on the cargo, but after a couple weeks of a broken aircraft sitting on the seabed ~400 ft. down, it's too late to do much about any fluids...

DaveReidUK

Agreed - there is little value there other than as scrap metal once they recover the recorders.
IF it turns out that they did experience a dual engine power loss - and - they can't...

Sorry, apparently I wasn't clear - the mention of FADEC was regarding newer engines which do have electronic protection of rotor speeds and burner pressure. The JT8D is purely hydromechanical...

Assuming they were talking high EGT, yes, I'd ignore an EGT over redline if the alternative was ditching (after all, it's not like there's going to be a usable engine left after a salt water...

Fuel contamination usually takes longer than a few minutes to have much effect - even av gas would be unlikely to take out the engines that fast. The JT8D is also unlikely to be severely affected by...

Open ocean would be rather more challenging than the Hudson River as well. In fact, this may be the first successful ditching of a commercial jetliner in the open ocean (although depending on the...
