Interesting discrepancy just being reported at a news conference being held by Germanwings right now.
They are saying the Captain did not enter the emergency code to open the door and there was no immediate explanation as to why.
I wonder if the door locking system was u/s. Not unusual for them to fail and go into the deferred defects.
See my reply earlier - that's not what I believe was just said. I speak German fairly well.
