Inspired by ttyymmnn's post about scrapping a C-130 I dug around and found this video about how they were scrapping B-52's. I remember reading about this a long time ago. IIRC they were being scrapped to comply with START or SALT or one of the other nuclear arms reduction treaties that we signed with the U.S.S.R. To comply with the treaty they had to be cut up in specific locations and then left out for a certain amount of time to allow the Soviets to verify their destruction by satellite flyovers.
