Personally I think my wife's theory of flight is much closer to the mark:-
There are lots of cute furry invisible creatures called Bernoullis that hang on to the leading edge and pull upwards. Like lots of cute furry things, they're not as nice as they seem at first glance, and are extremely bloody minded. So if you try and dislodge them by flying faster or pulling on the stick, they just pull up even more. However, ultimately you are stronger than they are, so if you pull hard enough you can dislodge them and you haven't got any lift any more.......
