uh 1 iroquois helicopter

At 2 A.M. on February 17, 1974, Robert K. Preston, a United States Army private first class, stole a United States Army Bell UH-1 Iroquois “Huey"helicopter from Fort Meade, Maryland, flew it to Washington, D.C. and hovered for six minutes over the White House before descending on the south lawn, about 100 yards from the West Wing. There was no initial attempt from the Executive Protective Service to shoot the helicopter down, and he later took off and was chased by two Maryland State Police helicopters. Preston forced one of the police helicopters down through his maneuvering of the helicopter, and then returned to the White House. This time, as he hovered above the south grounds, the Executive Protective Service fired at him with shotguns and submachine guns. Preston was injured slightly, and landed his helicopter. After being taken into custody Preston indicated he was upset over not being allowed to continue training to be a helicopter pilot, and staged the incident to show his skill as a pilot. He spent 1 year in prison, was fined $2400, and received a general discharge.

Massive “Shotgun” Tested for Vietnam-Era Helicopter Service

The XM-215 “Multiple Barrel Gun” consisted of 300 .22 caliber rounds equipped to either fire simultaneously or in a 40 second barrage, clearing landing zones of enemy troops. Four units, making a total of 1,200 rounds, were to be installed on a UH-1D Huey, but the system never made it out of the early testing phase. Concerns about friendly fire, down-wash from helicopters rotors affecting bullet trajectories, and the fact that is was essentially a one-shot weapon led to cancellation in 1971.
