At that time, many passengers on board saw the aircraft, which happened before air force one landed. At present, secret service and relevant air traffic control agencies have not issued a response on this matter. Although civilian drones don’t crash the aircraft directly, they can cause more damage than birds of the same size, according to the news agency. It is very difficult for air traffic control agencies to trace this fleeting event. Every year, the US aviation administration receives thousands of similar complaints from pilots that the UAV is too close to other aircraft or flying in the controlled area.
