[QUOTE="BillM, post: 4060520, member: 45785"] It had made several trips, as I understood it. Which is why it failed, probably. I used to be an aircraft mechanic for the USAF, on F-111D fighter-bombers. Just a young guy, only lasted about 16 months before I wrecked my knees. Then another decade as a still photographer, documenting equipment problems & testing on all kinds of aircraft, weapons systems, and accidents/incidents. My birds were notorious for springing fuel leaks because the epoxy sealant in the tanks would liquify in the heat & humidity. Also one of them was flown at Mach III, when they're only rated for Mach II. Damaged a lot of components, including the equipment bay doors for the avionics systems. Stress cracked, fasteners pulled through holes, etc cetera. Also USAF had to replace a bunch of B-52 bombers because the wing roots were cracking. When I was a young guy they had the sons of som of the original BUFF pilots flying them, and by the time I retired they were starting to have grandsons of the original pilots flying in B-52's. Ever watch a video of the BUFF launching, you'll see the wings flapping as they move on down the runway. I commented earlier that all solid substances I'm aware of stress fracture eventually. Learned that on the aircraft & autos I've worked on. Among other things. :) [/QUOTE]
