I will not comment on the technicalities of both accidents , not my area of expertise. although looking from the outside that is a lot of preventable accidents happening due of the failure of one sensor , or of one instrument/IRU ( i.e west air sweden ) and inability of crew to recognise it.
Whether it is a design issue , a training one, or other I leave the discussion to you guys.
But on the French Judiciary system , I agree with W. it is a scandal . Last week the trial of the people responsible for the collapse of CDG Terminal 2E , took place, that is 14 years after the event !
The worse ( that i know of) is the UTA DC10 bombing/accident that took place in 1989 in the Libyan desert. The last appeal , closing the case was done in 2008 , almost 20 years after the event , and the suspected perpetrator , a Libyan national. received a pre-trial in Tripoli in 2013 , still awaiting the full trial, we are now 30 years later..
