Wes wall and DERG, I see a straw man being demolished here. Who is looking for the pitot tubes? Who is silly enough to think they'll still be in the same condition as they were at the instant the plane died or entered its upset, your choice?
The object is to backtrack well enough to be able to go down there, locate some major
piece of debris, and from there search for the locations of the two important recorders, nothing else.
Obfuscating the discussion does no good.
