confuses me too. Everything I've read about how lift is created talks about air travelling faster over the top of an airfoil so that if 2 particles at the leading edge will meet again at the trailing edge even though the one that goes over the top has further to go and so must travel faster.
So how does the top particle know that it must speed up. What is it that causes the air to speed up? or for the air going underneath to slow down.
There is the deflection which I can see will push an airfoil or a kite upwards and I suppose will slow down the wind going underneath. And how does this speed difference give a pressure difference?, . I see pressure as being caused by there being more wind force on the underneath because of the angle of attack. As the angle changes the pressure changes. How do planes fly upside down?

This is a quote from the linked page

"When this happens, the air flowing over the top of the wing flows faster than the air along the bottom – this creates a pressure difference. Because of this pressure difference the wing is pushed upwards, which is lift!".

It does go on to talk about 2 forces, so how big is the deflection force compared with the pressure difference lift force?

There are only theorys why lift happens
