If someone asked you what provided the upward force, what would you tell them?

The wing cleverly throws a lot of air down and, as a result, wants to go up .. something Newton said a long time ago, as I recall ?

The effectiveness of this process (ie lift is desirable but drag is a bore) is a measure of the cleverness of the designer and the then present literature state of the art.

When you come to describe what's going on it's no different to any typical technical thing .. you can have the simpler or the more complicated explanation according to your needs and interests.

For the typical pilot a combination of the reaction and Bernoulli seems to be reasonably adequate ? One needs to have a passing bit of an idea about pressure distributions because pressure is the way a fluid transfers a force to a solid.
