Actually, that can't be the case, though everybody thinks it is. If Bernoulli's law were responsible for lift in aircraft, airplanes wouldn't be able to fly upside-down--and they can.
Yes, but not as efficiently, I believe, because the wings aren't designed to be optimum in that position. The fluid (air) is still accelerated and its pressure still drops, which is what creates lift. At least that was the example my high school physics teacher used, and i've never seen it refuted. Of course I've never observed a helicopter flying upside down, either! (In theory it should be possible, but I wouldn't want to try it!)
