Flypast

Imagine you are at a parade, and there are different vehicles and floats passing by. A flypast is like a parade in the sky, but instead of vehicles and floats, there are airplanes and helicopters flying by. They often fly in a formation or pattern, and they might make cool sounds with their engines or do tricks like loops or somersaults. People might watch a flypast to see how the planes move and to hear the cool sounds they make. It's like watching a cool show in the sky!
