Well, I looked at the home page ("airfoil") on that site and just
found out the school description of how wings work (faster air over
the top so less pressure, and the air must join back up at the far
side) is actually wrong (or at least vastly over simplified).
I never thought to question it. But then, how does an aircraft fly
upside down? No idea why that question never popped into anyones heads
at school !

At bit like A-level chemistry. I soon gave up trying to understand a
few things from first principles, since you came to a different answer
than the text book. I thought I was being thick, and it turned out I
was the genius after all !
