Bill & Alain,
Bill your references are spot on, but there is another that i learned during my time I was stationed at Mather AFB, CA and the B-52 unit was the 320th Bomb Group with (G) models. Apparently, with the G and the later H models the internal changes made for electronics and other instrumentation had a negative effect on the aircraft ventilation system which was especially obvious during hot weather. The smell which was compared to the flatus produced after eating a dead carcass or a baby diaper that has sat in the sun for a couple of days were fitting having experienced a small dose of it when a 320th buddy of mine gave me a tour on a weekend off. Their definition of BUFF - Big Ugly Fat Fart ........
Luckily for me, I graduated flight school in the upper tier so I got my choice of aircraft - the glorious F-4 Phantom. During my career I got to fly the D, E, and G models of the Phantom. The G model being the most hazardous of missions and saved for those of us who were considered a wee bit crazy by our peers. Thus closes another topic of historic trivia and as they say in French. C'est Fini !!
