I remember it too. I was an air traffic controller at Travis AFB at the time.
I remember both the F-86 crashed in Sacramento in the early 70’s as well as the Sun Valley crash in Concord.
I lived in Walnut Creek for a bit in the mid-70’s.
I assume the later was headed to Buchanan?
Concord used to be a nice, middle-class neighborhood.
Nowadays, it’s a lot of “Nuerteno’s” and “Suereno’s”
BTW, the Dems have their eye on turning TX into a Blue State at which point the US is done.
