Thanks to the below viewer who identified this filming location:
ABOVE IMAGE: Jim Rockford & his car is being chased by a helicopter. The scene takes place at an airport. The airport in this scene is surrounded by a fenced off area which contains abandoned residential homes, commercial property and these large airplane hanger type buildings.
In the background of this photo you can see a distinctive looking vehicle bridge.
It appears that the area around this airport was condemned due to either airport expansion or noise abatement in the late 1970's.
Based on the "LBeach" portion of these wall markings, I am guessing the Long Beach Airport.....
ABOVE IMAGE: This is the helicopter that was chasing Jim Rockford. Its tail number is: N59613.
