Why not exercise your minds as to the timely intervention of both the aircraft maker and the authorities as to the issues with the pitot equipment.
So that means you basically accept that if the pitots on an airliner fail it is OK for it to drop out of the sky ????
That is not seriously your take on this accident ?!
It has to be found out why after the assumed failure of the pitots it ended up where it did and what can be done in future to prevent this - be it by design improvements or training or whatever comes out of it should the boxes ever be found.
There will always be the possibility that the pitots will freeze. We will probably not be able to totally convince mother nature of not ever doing that again to any airliner.
