How can an airplane fly?

How can an airplane fly? Thanks to physicists such as Bernoulli, Newton or Venturi this is possible. We have several forces during the flight called sustentation, weight, impulse and drag. If we have in mind the law by Bernoulli which says pressure plus speed is equal, a constant which never changes, and we can see how the plane wing is inclined we realize what is happening. When air passes through the plane, on the top of the plane wing we can check speed increase instead of pressure. This causes the pressure on top to be lower than below the plane wing. Downward pressure keeps the airplane in the sky. I think it must be exciting to see into the cockpit how an aircraft can be flown around the world.
