The pilots are rumoured to learn their fate or fortune over the next day or so.
The screenshot of the company NOTAM that was leaked was, (in my view) a knee jerk reaction that was misplaced and has been withdrawn. The aircraft had been on the ground in Dubai for a little less than 24hrs and if it was powered down at any stage, the MCP would have defaulted to 10000ft. If the MCP was set to 0ft, perhaps it was not the previous crew who set this level, as has been suggested.
