I grew up in SE Montana in late 70s / early 80s and once while hiking in the hills outside of town I looked down at a B52 flying radar evasion missions.
Yes, I remember those flights. (We lived on a ranger station in SE Montana.) You could feel the vibrations as it approached, and then it would appear over the crest of the hill flying so low you could almost touch it, disappearing almost immediately over the next mountain. Very impressive flying.
