Never saw a Crockett but got a close look at an Honest John... was running a mortar range and was ordered to cease fire for 20 minutes because the rocket was coming directly over us on the way to the impact area. It had a concrete warhead, not a nuke. I just happened to be looking in exactly the right place when it came over the horizon, flew directly overhead, totally silent and slowly rotating. Gone in a flash. Most impressive!
