Hmmmmm ..?? I was raised in Sunnyvale (went to grammar school and high school there).
The only “base” I remember was Moffett Field in Mountain View. It used to be a navy air base, but I heard it was no longer a navy base and some other organization took it over because of the huge wind tunnel there. And .. Moffett Field was right next to Lockheed.
Of course, I haven’t been to the Bay Area for quite a few years, so a lot of things could have changed by now.
Now NASA uses Moffett Field... But what I saw was just a large blue bldg somewhere there with a dozen or more satellite dishes and all surrounded by chainlink. It said USAF something or other and was NOT surrounded by runways. There was something on TV about it one time, too...
