Rushed Approach....the truth is nobody knows what brought this aircraft down...
Terrorism is far more unlikely (given the current political climate) on a French jet than on an American jet...but still possible....terrorism follows a cause (however they justify it)...it is just that in the current political climate, there is no cause against France in International politics....which makes a bombing unlikely, but still possible.
Weather is another factor...BOAC 707 at Mt Fuji springs to mind...an aircraft relatively new, yet was smashed by Lee Turbulence off Mt Fuji, no chance even for a MayDay. Other aircraft went past the area and did not report many problems, but again, it means nothing...I have seen many aircraft do missed approaches one after the other, then about 4 or 5 are able to come in when weather changes, and bang, all shut again, and no other aircraft can get in...unpredictable.
As someone who's flown Airbuses for a while, can you explain to those who have not, what the worst case scenario would be at that height, at .82 or .83 and what window of opportunity you have to regain control in the case of a violent upset?
