These are photos of the fuselage of aircraft that ditched in the Hudson River being transported through New Jersey. The aircraft played no small part of the survival of those on board.
Note the lower rear portion of the fuselage is crushed and the belly skin is gone and wrinkles are visible on the upper side of the fuselage closer to the over wing exits. The aircraft ditched with the nose high and the rear fuselage making first contact with the Hudson River. This initial impact crushed the lower fuselage (damaged in "tension"), actually bending the entire fuselage as if the tail was pushed up which is where the "wrinkles" come from (damaged in compression).
Great job "Sully", and the aircraft did its job as well by absorbing and distributing the unusual applied loads from the ditching to remain relatively intact.
