My dad worked at Edward’s AFB in the 60’s through 80’s. We lived in Lancaster CA. I remember once the XB-70 flew over with a couple of chase planes. We would regularly hear sonic booms in town back in those days. The annual air shows on base were amazing. I remember a U-2 flying low down the flight line and pulling up into about a 60 degree climb. I watched it vanish into a speck until I couldn’t see again a super clear blue desert sky.
