Abstract: At least a first rescue device for receiving rescue is configured on a bottom side of an aircraft and at least a second rescue device for providing rescue is configured on a bottom side of the aircraft. The first and second rescue devices can be optionally configured. For a small aircraft, only the first rescue device for receiving rescue can be configured. For a large aircraft, both the first and second rescue devices for providing and receiving rescue can be simultaneously or optionally configured. When an aircraft with the first rescue device for receiving rescue suffers loss of power, insufficient power, or control difficulty, another aircraft with the second rescue device for providing rescue can fly on top of the former and their first and second rescue devices can be linked together so that the troubled aircraft can be pulled away to land in a safe place.
