Your dad likely worked alongside my mom's uncle. He worked in St. Louis starting in the late 60's, ended up being transferred out west, if i remember correctly. Coincidentally, his father lived close to the Illinois river in a town named Meredosia. During the 70's and 80's the family and i spent many weekends there for fishing and camping...we would see and hear the Phantoms (from ANG in Springfield) flying relatively low above the river or Lake Meredosia. Watching them and hearing the sonic booms gave me goosebumps.
Very cool to watch, especially for kids. I was in my early teens then, also a military aircraft enthusiast back then.
