NAS Miramar from above showing the runways back in the day. The primary was 24R/6L at 12,000 ft. The parallel is, of course 24L/6R at 8,001 ft. It contained the simulated flight deck for Field Carrier Landing Practice (FCLP) training. Then there is the diagonal runway 28/10 which was 5,000 ft. long if memory serves me correctly. Photo most likely taken after Miramar was transferred to the Marine Corps.
