A highly skilled person has disproved a long-held opinion of mine: that it’s impossible to put a transport category aircraft down on water (from flight speed) without massive structural failure.
As always, credit should also go to the hundreds of people who design things like APUs, ram-air turbines, hydraulic pressure reservoirs, and the other boring pieces that allow an A320 with both engines disabled to continue acting like an aeroplane instead of an aluminium brick.
I am guessing this might be the new textbook justification why the APU should be operable & running for takeoff and landing. Oh my yes.
