A U.S. Army soldier stole a Bell UH-1 helicopter (pictured) and landed it on the South Lawn of the White House in Washington, D.C.

The Bell UH-1 Iroquois is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military.

On February 17, 1974, U.S. Army Private First Class Robert Kenneth Preston (1953–2009) took off in a stolen Bell UH-1B Iroquois "Huey" helicopter from Tipton Field, Maryland, and landed it on the South Lawn of the White House in a significant breach of security. Preston had enlisted in the Army to become a helicopter pilot. However, he did not graduate from the helicopter training course and lost his opportunity to attain the rank of warrant officer pilot. His enlistment bound him to serve four years in the Army, and he was sent to Fort Meade as a helicopter mechanic. Preston believed this situation was unfair and later said he stole the helicopter to show his skill as a pilot.

The South Lawn at the White House in Washington, D.C., is directly south of the house and is bordered on the east by East Executive Drive and the Treasury Building, on the west by West Executive Drive and the Old Executive Office Building, and along its curved southern perimeter by South Executive Drive and a large circular public lawn called The Ellipse.

The White House is the official residence and workplace of the president of the United States. Located at 1600 Pennsylvania Avenue NW in Washington, D.C., it has served as the residence of every U.S. president since John Adams in 1800 when the national capital was moved from Philadelphia. "The White House" is also used as a metonym to refer to the Executive Office of the President of the United States.
