What are the advantages and disadvantages of unmanned combat aircraft compared with manned combat aircraft?

UAV technology can also be enlarged when it is mature. The advantage of UAV is that it does not need to consider human factors, so the speed, maneuverability and range of UAV can be greatly improved in the future, and the training time and cost of pilots are reduced, so the cost and service period are also greatly reduced. At present, it is mainly used for reconnaissance and some simple bombing missions, but once the UAV technologies like Falcon and X37B in the United States are mature, the UAV will be all-powerful and even launch attacks in space. Compared with the future of unmanned aerial vehicles, the advantages of manned aircraft will be less and less, because the load resistance and limited physical strength of human beings are far from enough in mobility and speed. The advantage is that it can be handled better in an emergency, such as controlling the plane not to fall in a crowded area after the crash.
