I was stationed at MAFB from 1974 to 1975. I repaired B52 avionics equipment.
At the time the civilian airport was like, 13 miles away.
They didn’t even have a tower it was all visual, radio, and telephone.
Hard to see how civilians and a B52 would ever be in the same airspace given the strict restrictions that exist near MAFB airspace.
It may have changed but MAFB had Nuclear armed aircraft on “ground alert” at all times and could be in the air at anytime.
I thought MAFB is where B-1 Bombers were based out of for years. I might be wrong though.
I lived about 10 miles off the end of a SAC wing USAFB. Nixon was President? Ford? (Not Jimmy Carter.)
Occasionally over the years, there would be a launch of 2 or 3 B-52s, but one non-winter day, SAC launched everything.
By the time that a B-52 was overhead, it was about 2,500 - 2,800 ft and fat. Much lower altitude than usual: Not a drill.
Each B-52 was about 3 - 4 minutes apart. 10 B-52s total.
Usually, I would run outside, watch a B-52 fly by, go back inside . . . but by the time 5 B-52s went by, I was really beginning to wonder . . . and turned ON the shortwave radio.
