This discussion is ridiculous. Contaminated wing. NoGo. Thats it. Nobody cares about dry snow or whatever.
It flys in this video. Yes. But at what margins? The wing is not clean, Critical AOA WILL reduce, thats a physical fact. When will it stall? I don't know, and you don't know and those pilots also didn't knew. And because we all don't know, there is only one solution: keep you wings fu***** clean.
Maybe one gust, one engine failure ore a higher rotation rate could have lead us to disaster. This may work 1 time, maybe 10 ore 100 times. Maye a thousand times, but one day it won't work.
Clean aircraft is clean aircraft is clean aircraft.
I am shocked about this discussion is 2012.
