This B-52E aircraft was used by General Electric in the 1960's to test their TF-39 engine and was disposed of in the desert after the tests.
Fast forward nearly 30 years later to 1991 when the Strategic Arms Reduction Treaty (START) was signed and 350 nuclear bombers were being destroyed as part of the agreement. The Russians saw this bomber on aerial footage and soon after, the US destroyed the aircraft by placing explosives in the fuselage.
