jcjeant;
It seems that for the BEA recovery was impossible .. unless a miracle ......
On reflection, I believe the BEA have developed the Report on the basis that their mandate was to determine the actions and/or events that lead to the aircraft departing the Normal Flight Envelope. The report then covers factual information concerning the LOC through to impact.
Consequently, they are very vague on possible alternative outcomes for which no validated data is available, and it is up to the airframer and regulator to establish procedures that can be used in a LOC situation where the envelope has been "extended".
