I wouldn't be surprised the recorders are stuffed eg Jeju; possibly the rear one "died" on the power interrupt and the front one got smashed up in the crash

Always possible, however since a pilot made a radio call there was some emergency leve l power available, which suggests the EAFR would be powered.

The Jeju recorders were okay if I recall correctly, they just had no input, was that the case?

Somoeone made a good point above about the German Wings FDR/CVR being available the next day after the aircraft was aimed at the ground like a missile. These things are built tough, as you know, this may be type specific but….

Fire (High Intensity) - 1100\xb0C flame covering 100% of recorder for 30 minutes. (60 minutes if ED56 test protocol is used)
Fire (Low Intensity) - 260\xb0C Oven test for 10 hours
Impact Shock - 3,400 Gs for 6.5 ms
Static Crush - 5,000 pounds for 5 minutes on each axis
Fluid Immersion - Immersion in aircraft fluids (fuel, oil etc.) for 24 hours
Water Immersion - Immersion in sea water for 30 days
Penetration Resistance - 500 lb. Dropped from 10 ft. with a \xbc-inch-diameter contact point
Hydrostatic Pressure - Pressure equivalent to depth of 20,000 ft.

having a brand new FDR lab, might not be sufficient in case you have to reconstruct the melted data access paths to the core memory modules

Well if a brand new, completed in April purpose built facility is not up to the task, then what hope is there. That is why it was built, for just this eventuality. Knowing a little about things, I would venture that know how is more critical here than the equipment available.

Either way, the US facility is avaible, so why take a week to decide to send it there?

Here is their reasons…

Some interesting words in there. Yes Minister.

Training Captain who has just witnessed a trainee turn both fuel control switches off.

The FO had 1128 hours on type. Unless he was a slow learner he was not in training.

People please, read the report before posting.

A huge generalisation which I find to be untrue.

We know that the captain was a trainer and as such, it is likely that he was used to running details both from the instructor station and either seat.

A few people have alluded to his training role. Was he a line training captain or a sim trainer as well? I have not read anything to clarify this but of course I could have missed it.

I think that the teams of class action lawyers, who are no doubt circling, will ensure that does not happen.

As I said very early on in the other thread about this accident, the party in the clear will leak against the other party.
I fully expect to see a transcript of the CVR in the next few weeks. It will be leaked.

If suicide, this is the only part of flight where the FDR will not identify which pilot is responsible.

Why is that then?
