Not exactly. When an airplane wants to fly, it must have upward lift. The upper wing of the plane is convex and the lower wing is flat, so that when taking off, the upper wind speed is relatively high and the lower wind speed is relatively low. The higher the speed, the lower the atmospheric pressure. In this way, the atmosphere gives the plane lift, which can be understood as the atmosphere holds up the plane. In addition, the engine of an aircraft is generally a vector engine, which forms a certain angle with the ground when taking off, which not only gives the aircraft speed, but also
