There apparently was a lack of oxygen, which is usually the case when the cabin is de-pressurized.

We got what we wanted from the flight.

The only fortunate event in the investigation is that we have the flight data recorder.

This (loss of pressure) occurred during the ascent ... We are still investigating why the pilots continued their ascent and did not respond properly.

It's in a bad state and, possibly, it won't give us the information we need. Both boxes will be sent to Paris where a French committee will help us and the foreign experts that are here to decode.

What troubles us is that the automatic pilot was functioning up to a certain point, and then it was disengaged, possibly by human action.

I stress that a flight reconstruction of this size has never happened before in Greece and I'm of the impression that the whole scenario of this flight has never happened before in the world.

We don't know if we will be able to get something from it.
