Boeing is developing a flying machine that is invisible to radar and unmanned by humans.

The project is called the Phantom Ray.

The Phantom Ray is scheduled for demonstration in December 2010.

The craft will be tested for six months on reconnaissance test missions.

The project is being sponsored by the Defense Advanced Research Projects Agency (DARPA), which has contributed $942 million.

The Phantom Ray will be capable of bombing, reconnaissance and mid-air refueling missions.
