Stealth Technology Spreads

The significance to this article on Pakistan's development efforts on a stealthy cruise missile is fairly straightforward, this stuff is not rocket science.

The basic physics of stealth have been known for 40 years, and the technology to cluster inexpensive computers to do the calculations is also well known.

The implementation is not a natural monopoly of the USA...It isn't rocket science^*.

^*I spent much of the late 1990s as a rocket scientist, or at least a rocket engineer. These days, rocket science is not rocket science.
