I live about 30mi SE of Travis AFB in California. For about 5 days in a row, there was 2 or 3 flights of fighter jets coming from the direction of Travis, and bookin' it towards the SE Very high, very fast, and VERY loud. My wife, son, and son-in-law all saw at least one flight, But me, the airplane guy, never did see one. SON-OF-A .......!

Travis is a big logistics base and has no fighter aircraft based there. There is, however, an Air National Guard base in Fresno which is in the general direction they were headed. They fly F15's

Fun fact. The shadow of an aircraft caused by the sun will be the size of the aircraft regardless of the aircraft's altitude.
I haven't researched this myself, but there are posts on the Internet that disagree. I can naturally find a post that disagrees with anything, it's just this one sounds pretty credible. The argument is that the theory would be true only if the sun were a point source (it isn't), and there were no atmospheric effects. In that case, the theoretical geometric answer would be true. The shadows would also have perfectly defined edges, which this one doesn't.

Disagreement post to read if you really want your head to hurt: Is the Shadow of an Airplane the Same Size as the Airplane?
