Gli incidenti succedono: Un estratto da "comando e controllo"
Eric Schlosser

The Mark 36 was a second-generation hydrogen bomb. It weighed about half as much as the early thermonuclears—but 10 times more than the new, sealed-pit bombs that would soon be mass-produced for SAC [the Strategic Air Command]. It was a transitional weapon, mixing old technologies with new, featuring thermal batteries, a removable core, and a contact fuze for use against underground targets. The nose of the bomb contained piezoelectric crystals, and when the nose hit the ground, the crystals deformed, sending a signal to the X-unit, firing the detonators, and digging a very deep hole. The bomb had a yield of about 10 megatons. It was one of America’s most powerful weapons.....

...The fire lasted for two and a half hours. The high explosives in the Mark 36 burned but didn’t detonate. According to an accident report, the hydrogen bomb and parts of the B-47 bomber melted into “a slab of slag material weighing approximately 8,000 pounds, approximately 6 to 8 feet wide and 12 to 15 feet in length with a thickness of 10 to 12 inches.” A jackhammer was used to break the slag into smaller pieces. The “particularly ‘hot’ pieces” were sealed in cans, and the rest of the radioactive slag was buried next to the runway. Sidi Slimane lacked the proper equipment to measure levels of contamination, and a number of airmen got plutonium dust on their shoes, spreading it not just to their car but also to another air base.
