Oh wow... yea man, that had to have been awesome! You were right there when they were operational! I was around as a young kid and I saw one at an airshow down in Florida with my Grandfather who was a long time engineer with NASA... I have been in love with the SR-71 ever since. As a kid, I remember it being EXTREMELY loud, haha... those J-58 engines had a sound of their own. You were a part of something very special... I know my Grandfather felt the same way with NASA, being around from the beginning of the Mercury days up through Apollo... he was just happy to "be a part" of it all.
