If the Bernoulli explanation is right, and the lift comes from the shape of
the wing slowing down the air on top, I've never been able to understand why
stunt pilots can fly their airplanes upside-down. Wouldn't they be pushed
down to the ground? The Newton explanation, by contrast, holds good for
upside-down airplanes too.
