US intelligence is now warning that Iraq may use its unmanned "drone" planes to deliver chemical or biological agents to targets inside the US. This causes "real concern" for US officials, even though there is no hard evidence to back it up.
The unmanned aerial vehicle (UAV) was used in Powell's presentation to the UN to show just how crafty Iraqi model-airplane enthusiasts have become. Powell said one of these UAV's could carry a "spray device" and fly an entire 310 miles nonstop.
These drones were at first only considered a threat to Saddam's neighbors, but now US intelligence fears they may be smuggled into the US and deployed against American cities. http://foxnews.com/story/0,2933,79450,00.html
