The Pentagon plans to fire a missile at a rogue U.S. spy satellite that threatens to crash to Earth in March. But don't panic: even without a missile strike, the chances of a huge chunk of spy-gear crashing on your head are fairly low, General James Cartwright just told CNN. Also, "the blogs" are wrong about the danger of classified info surviving the heat of reentry. The main reason a Navy ship will knock the thing outta the sky in the next week or so? The satellite's hydrazine fuel, which the military doesn't want coming back to Earth. Plus, target practice.
