Maintenance personnel remove blades from a Black Hawk Helicopter. After the aircraft landed at the loading docks of the convention center in downtown Dallas, the aircraft were then towed inside the show room floor. Large aircraft such as the Black Hawk could not fit through the door unless several of the rotor blades were first removed. Teams of aircraft technicians were standing by as the helicopter landed to quickly remove the blades and then replace them once positioned inside the exhibit hall.
