I'm not sure how it is at Ft. Sill, but in Manhattan, KS the range is right next to town and in the middle of well populated ag areas ... not to mention K State is pretty darn close. Driving down the highway you can look at the hill tops and see the barrels swinging from side to side. Nothing like laying in bed at night listening to the booming of distant thunder or whatever is in bound
At your age the FB 111's may have been out of NH or NY ( the NH base closed in the early 90's )
The F111's would have been from Cannon AFB in Clovis NM.
The F111's were at cannon back in the 70's up until about 2003 or 2004 when they went to the bone yard at DM and were replaced with F16's. These were F111 D models, Cannon was the only base to have them. They originally started with about 80 acft but lost several thru crashes when flying hi speed low level flights. The pilots usually chickened out and turned off the auto pilot which did them in.
