"MAYDAY"
...requesting "Emergency Descent"
....initially cleared ...to FL350
...request for further descent to FL250.
...The aircraft announced a "Pressurisation faliure" and
...requested FL100
Request??? Are you sure you have it correct? Who "requests" an emergency descent?
Maybe it was only a slow leak and the guys felt they had the time to take a few precautions with the descent. That could explain the lack of news coverage but not the MAYDAY.
Or maybe the thread starter hasn't reported it accurately here. That'd be a first! So many conclusions to jump to, so much baseless speculation to put forward... where're all the walts, wannabes and armchair drivers?
