While I’m sure that the process for manufacturing “Fogbank,” the code name for a component in Trident Missile warhreads as supposed to be a top secret, I don’t think they meant this secret:

PLANS TO refurbish Trident nuclear weapons had to be put on hold because US scientists forgot how to manufacture a component of the warhead, a US congressional investigation has revealed.

The US National Nuclear Security Administration (NNSA) “lost knowledge” of how to make a mysterious but very hazardous material codenamed Fogbank. As a result, the warhead refurbishment programme was put back by at least a year, and racked up an extra $69 million.

This seems to be a process-level analog to a friend’s comment that, “encryption equals data loss.”

Obvious solution - try mixing all the dangerous liquids confiscated at airports. Some combination of showergel and toothpaste might just work.
