i think the pilots have some control of the 737
because of the photograph , the wing section is in pretty good shape compare to the austral fall in 1997 in uruguay that the biggest piece found was of 2 inches , the similarity of both is the fall from almost same flight levels , its my opinion, as you can apreciate the ldg gear is also down, but as i said before please do not judge , lets wait fot the cvr and the fdr best regards , have safe flights
