Where was G.Harry Stine, NAR #2? He was working at WSMR around that time. Why weren't those people in a blockhouse? If it blew up they could all have been killed.
There are many Nike vids on Youtube, some in color, showing a lot of details. It was designed by the phone co! Western Electric. Could use 3 different sizes of nuke warhead.
The radar targeting system was pretty funny, they could not combine all the axis on one screen, so they had THREE, one guy at each one. For elevation, azimuth, and range.
The analog control system had a update rate of 1 second. Wow. But it could hit planes for sure, many tests were done.
That simulation system was based on an analog computer, you can tell by the rows of pots, and digital was not up to it yet in those days, probably due to programming limits.
Surplus Nike motors were used on rocket sled tests in New Mexico, I saw several, some supersonic. They have parachutes that can open at Mach 2, Kevlar webbing.
If you have never seen one, find a vid on the Sprint missile, it is faster than heck.
