Well Gimble....
Maybe a transcript that contains any last words you might like to get out would be nice....an analysis of the tape that comes up with the usual "I am outta here statement...." would at least indicate you were not knowing of the cause. Short departure comments like...."Ah....(insert your favorite four letter word)! for example.
Now if you were cool, calm, and collected....scratch calm....afterall you will be cool when collected following one of these events...and did have the presence of mind to say something about what brought on your suddent free fall....it would help.
But what the heck...the AAIB folks need a good puzzle every now and then....keeps them earning their paychecks.
