Thanks for putting that tool in his place.
Maybe the idiot can tell us how effective closing the outflow valve (2.5 Sq/ft?) would have been when probably 150+ sq/ft of lower aft body fuselage skin was ripped open by the impact.
The ditching sw also closes the pack inlet doors. With those doors open water would enter and tear off the under-fuselage fairings. Had those doors been closed it is entirely possible the body skin would not have been torn.
