Hooper Heliport is located on the roof of the Piper Technical Center, the world's largest rooftop airport. It is centrally located between Los Angeles Union Station, Chinatown, and Downtown. It is home to the Los Angeles Police Department's Air Support Division which is the largest police aviation unit in America with 19 helicopters.
The Piper Technical Center is also used as a parking lot for some of the LAPD's motor pool including marked and un-marked units, vans, buses, motorcycles, and the V-100SWATarmored cars.
Hooper Heliport served as home base for the fictional police helicopter Blue Thunder in the 1983 motion picture of the same name, while construction of the heliport was still being completed.
