1. THe complete explication (and accusation) was issued after only 48hours.
2. Other experts claim "normal breathing" would NOT be picked up by recorder.
3. No specific place of impact on ground.
4. The prosecutor said that one could hear the Co-Pilot change altitude settings whereas other experts claim this makes no sound whatsoever. The change of settings would be picked up by the other flight data recorder which - well - have they even found it or mentioned it?
5. At no point has there been any reference to the sound of deadbolting the door (now this makes a sgnificant sound) after the PIC tried to re-access the cockpit.
2. Who are these experts? For the purpose of CVR recording, the headset boom microphones are always live. No button pushing is required. Surely a microphone placed a centimeter or two from the mouth would pick up normal breathing (It's already been stated in this message thread that other crew members can sometimes hear breathing).
4. It was mentioned earlier that some make sounds, some don't (an option).
5. There are different types of deadbolting. Some are relatively quiet. Having said that, most likely the F/O's seat would have made a noise if he stood up to walk to the door (the investigators did say they heard the captain's seat earlier).
