Have heard on "good and reliable" authority:
"Aircraft hit CB...experienced +/- 100 knot windshear. Autopilot disconnected ...Power failure to screens...Airframe breeched...Rapid decompression...Followed by flight control losss......Entire event 14 minutes"
Must have been a long 14 minutes !!
Not really a long 14 minutes necessarily, the rapid decompression at the probable max operating altitude to fly over weather like this was probably violent enough to knock most people out rather quickly.
The distance of the debris field will suggest at what altitude the airframe breach occured giving insight into how long most were consious.
