An internal Pentagon investigation of the U.S. missile defense system found numerous quality control problems with the troubled "kill vehicle" that is intended to destroy incoming ICBMs. In one case, a manufacturing operation had to be stopped because the parts kit included a screw without threads.
Screws without threads are called nails!
Do you even science, Mark?
It seems to me like the Pentagon just needs to buy some hammers. I've got some $3,500 ones I bought from the local Wal-Mart they can have. I'll even give them a 10% discount if they buy in bulk.
