Factual error: Lt. Harp is told by Capt. Leo that the Lieutenant has 56,000h of UAV flying time, That is ridiculous. Even seasoned pilots of the Military Airlift Command do not have that many hours. Drone pilots can fly up to 1,800 hours a year, and Harp hasn't been flying drones for 31 years straight.
Factual error: The Captain fires his Glock and it's dry. Firstly once a Glock's magazine is depleted the slide is held back by the empty magazine and slide stop. Secondly he pressed the trigger twice and the gun made a clicking noise twice. Glocks are striker fired, when it's empty the trigger can only be pressed once and after that the trigger stays to the rear unless the slide is racked or a new magazine is inserted and the slide is racked or slide stop is depressed.
