>>508525729 (OP)There is a neat story about it that I know...
The outside of the airplane is coated in kind of paint that has microscopic ball bearings which are applied to the plane in airesol form along with the black paint. The microscopic ball bearing are supposed to cut down the radar signature .
In the 1980s the Soviets where desperate for a sample of this stuff. for obvious reason, so they concocted a fiendish plan! They found a some pencil pusher administrative employee who worked in the plant, which I believe was in Virginia, he had gambling debts and they bribed him like 100k. He didn't work on the production floor, but he had to walk through it every day, so the KGB agents gave him special 'sticky' shoes so that they could get their sample.
If you have ever seen that show 'The Americans' which is a great show, it's in that, but apparently it's a true story.
