Lost stuff woth big bucks eh?
How about
On Feb. 5, 1958, a B-47 bomber dropped a 7,000-pound nuclear bomb into the waters off Tybee Island, Ga., after it collided with another Air Force jet.
I bet the FedGov would pay big for that....
Remember too it is in a corrosive environment, so cut that to less than half of the average shelf-life.
