The A320 FBW system did not/could not;
a: turn the aircraft towards the Hudson,
b: Commence the checklists that may have restored thrust,
c: Instantly calculate the glide distances to La Guardia and Teterboro and conduct a risk assessment as to the probability of a successful landing at either.
d: alert the Cabin crew and passengers in a timely manner to prepare for the ditching.
e: flare the aircraft at to appropriate time to reduce the rate of descent; had the aircraft been flying itself it would have struck the water at over 1500 FPM, travelling another 50 knots faster with Flaps UP!
f: make sure that everyone was off before it evacuated.
Langweisches premise is thin, wrong and downright insulting. What some people will do for a buck!
