1972 B-52C Lake Michigan crash
On January 8, 1971, a Boeing B-52C Stratofortress (serial 54-26660) of Strategic Air Command crashed into northern Lake Michigan at the mouth of Little Traverse Bay near Charlevoix, Michigan, while on a low level training flight. All nine crew members aboard were lost. No remains of the crewmen were recovered. Parts of the aircraft were retrieved from a water depth of 225 feet in May and June of 1971. The structural remains included parts of the wings, all eight engines, the tail, crew section, landing gear and wheels, plus numerous smaller parts of the plane. Oceans Systems, a Florida-based salvage company, carried out the recovery mission.
==Background==
Strategic Air Command was formed by the United States Air Force after World War II to provide an active defense against any surprise attack by the Soviet Union. Though it had been an ally against Germany and Japan during World War II, the Soviet Union showed a propensity to instigate problems with Britain, France and the United States by 1948. In August of 1949, the Soviet Union exploded its first atomic weapon and by the early 1950s had exploded a hydrogen bomb. The war of words between the two superpowers escalated during 1950s and 1960s into a nuclear weapons race and a race to develop new ways to deliver those weapons. By 1970 the United States was using a "Triad Defense System" composed of nuclear submarines armed with nuclear missiles, land based intercontinental ballistic missiles with nuclear warheads and bombers capable of delivering hydrogen bombs on enemy targets. The Boeing B-52 Stratofortress bomber had been designed in the early 1950s by Boeing Aircraft Company to give the United States Air Force the capability of delivering nuclear weapons far inside the territory of Soviet Russia. The planes were to fly at high altitude with enough fuel to hit their target. In May 1960, the Soviet Union made known its capability to shoot such high altitude planes out of the sky by using a surface to air missile to strike CIA pilot Francis Gary Powers' U-2 spy plane over Russian territory. From that point on, the high altitude B-52 had to be modified to conduct missions at low level, something it was not intended to be.
