Airplanes will be far more advanced in the future.
Airplanes fly because they are able to generate a force called Lift which normally moves the airplane upward
When the Thrust produced by the engine(s) is greater than the force of Drag, the airplane moves forward. When the forward motion is enough to produce a force of Lift that is greater than the Weight, the airplane moves upward.

While any part of the airplane can produce Lift, the most Lift comes from the wings.
