That's an unusual and epic photo.
I remember when the YF-16 was first being introduced and paraded around, before there were any of the FSD Grey Falcons.
It was just this red, white, blue, and black, strange-looking plane with blended wings and a viper-like leading edge root extension planform, with a big intake underneath.
It did things in the air no other fighter could do when looking at maneuverability, and was always a crowd-pleaser.
That was in the 1970s when things were much different. They turned one of the YF-16 prototypes into the F-16CCV demonstrator.
My dad ended up working on it later with some of the advanced systems being developed for the F-16C subsequent production blocks, originally planned for Block 30, but later implemented on Block 50/52.
One of my best friend's dad was the chief test pilot on the F-16 CTF at Edwards, while another worked on developmental engines for DEEC on the F100 improvements. I remember going over to the pilot's house and watching his HUD video practice sessions for the Edwards open house, and hearing how guttural and physical the whole thing was.
Flight restrictions were more relaxed back then, as it was at the height of the Reagan years, which was awesome.
