I hardly think Kenny qualifies as Big Ugly Fat F#cker. I have tons of Vietnam stories about them. My dad put gas on the KC135's that fueled up the '52's from Guam (as well as his share of BUFF's) before their bombing runs and a guy I knew years ago used to be a bomb-loader on Guam around the same time. His story about one whose wings dropped off during takeoff due to metal fatigue while loaded with bombs was downright scary.
BTW, IIRC, that train is in Thailland.
