The Patriot Flawed?: "In the Pentagon's multi-billion dollar arsenal of weapons, one weapon the government has already spent more than $6 billion on has not only had trouble doing what it was designed to do—bring down enemy missiles—it also does something it was not designed to do.

"That weapon is the Patriot missile system. And the thing it's not supposed to do is bring down friendly aircraft."

"When the U.S. and its allies invaded Iraq again last year, the U.S. Army deployed Patriot crews across the battlefield. And it wasn't long before those crews knew they had a problem."
