Hi all. First post on PPrune, unfortunatly for the worst reasons
First things first: I'm just an aviation enthusiast, nothing more... A "MSFS Pilot" as you (pro) guys like to refer to us. I just hope that doesn't make me some kind of "persona no grata"...
That said, just a couple thoughts about this:
Besides the ACARS (automated) message(s), there isn't (
AFAIK) a single registered (reported) comm attempt or distress message. Not on HF, not on VHF (guard, for instance), SATCOM, nothing that we know about.
That just makes me believe in an (unknown caused) explosive decompression that also rendered the aircraft's comms U/S. The "decompression" alarm (ACARS) may somehow corroborate it.
Forget the "causes" (T/S, CB, severe turbulence) and focus on the "outcome": it was fast. Way too fast.
