Those two bases are less than 30 mile apart. There are a bunch of restricted air space to the north and northeast near Edwards as well as bombing and gunnery ranges for them, the military bombers and fighter bombers to practice blowing up targets ,
My wife's uncle work at Lockheed as an aeronautical engineer for many years,(1950s up to the early 1990s) helped design the U2 and the SR 71 as well as others that he wouldn't and couldn't talk about, IE the F117 when it was being built, tested and put into service without notifying the public.
I had one of the B2 bombers fly within a 1/2 mile of me when we were flying from Hesperia, CA up to Bend, OR on one flight in the mid 1990s, Lockheed test flew everyone of them before releasing them to the Air Force, they had a F 5 chase plane filming the entire flights I was told later by an AFB 42 employee
