FILMING

The first season was filmed on location in Hawaii at Schofield Barracks. For the second and third seasons the series was filmed around Los Angeles, California in order to reduce costs. This also enabled the producers to redress a studio backlot as Saigon. The move also meant reusing the same locations, notably a small river with grass on one bank and woods on the other which turns up in a number of episodes. A lot of filming was undertaken on the old set of M*A*S*H. Helicopter scenes with McKay were filmed on the ground with the rotors running.
