At least one real-world buried nuclear warhead has actually been documented however , but American and in the USA , rather than Israelian in Syria . The plutonium pit of a Mark 39 nuclear bomb warhead remains buried 33m deep in a North Carolina field , now fenced-off , following the fatal 1961 Goldsboro B-52 crash . Many B-52 Stratofortress crashed whilst carrying live nuclear warheads on training flights , mostly inside the USA , between 1961 and 1968 , but many have been recovered
