There's an interesting story about how the CIA got wind that the Soviet Union was trying to steal the US's space shuttle plans in the late 70's/early 80s. So, they mixed in some fake formulas for the heat shield tiles, among other defects, which Russia copied and built. Their "Buran" shuttle made 1 flight and mostly burned up on reentry due to the faulty heat tiles. If you ever see any pictures of the Buran's, they look identical to the US's shuttles, because they were using stolen designs. My aunt was actually directly involved in uncovering this. It would actually make a great movie.

Edit: Here's a really cool video some guys made when they broke into the facility in Kazakhstan where the Burans currently sit, slowly falling apart. https://www.youtube.com/watch?v=-q7ZVXOU3kM
