So how do planes fly? I don't know. It could be a packet of air is seperated at the leading edge of the wing. It then goes over/under the wing and the packet meets up again at the trailing edge of the wing. Due to the curve of the upper surface of the wing, the air must move faster to meet up again at the trailiing edge and (Bernoulli principle) this means lower pressure which causes lift. This is wrong. Possibly.
Another explaination is that the wing just directs air downwards causing lift. The lower surface trailing edge just forces air down. Air on the upper surface follows the curve of the surface (Coanda effect).
Neither seem to explain how a plane can fly upside down. How do planes fly? I thought this would have been science 101 stuff.

Air separated by the leading edge of the wing is, in almost all situations, deflected at two different angles. Whichever angle is greater become the lift side of the wing. Remember that 99 percent of the time the wing is being forced through the air at some angle.
Even a flat wing can do this, just buy another balsa plane from the toy store to test it.
