In comments to the post on the B-36 Peacemaker, a joke was made by "rickn8or" that the six Pratt & Whitney radials and four GE turbojets on the Big Stick must have made a heck of a "carbon footprint." This, of course, paled compared to the carbonized footprint it could leave with its 42 ton maximum bomb load.
On May 22nd, 1957, a B-36 preparing to land at Kirtland AFB in New Mexico had a bit of an accident, dropping its Mark-17 thermonuclear gravity bomb into the desert below. Although the bomb's conventional explosive trigger detonated, the nuclear payload on the unarmed weapon was not triggered.
Anybody want to bet on the size of the "carbon footprint" in the bombardier's trousers?
