With A/T's in manual and you forget to pull back the levers
Allowing for the fact it is only a hypothetical case, it is unbelievable any competent and qualified on type pilot would forget how to fly with manual throttles.
Also, it will be most interesting to see the reason why an all flaps up landing was conducted; especially with approach and landing speeds around the 185 knots. That is a serious speed indeed and rarely practiced in the simulator.
If, according to reports, the captain elected to direct the co-pilot to conduct the all flaps up landing under such critical circumstances, it would indeed be a courageous decision (as Sir Humphrey would surely attest), that speaks volumes of the touching faith in the co-pilot's competency. In any case, unless there was a technical problem that prevented flaps and leading edge devices from not operating, there should be no reason that a normal Flap 30/40 should not be used up to the maximum crosswind component - whether windshear/turbulence was present or not. .
