The Navy's new drone being tested near Chesapeake Bay stretches the boundaries of technology: It's designed to land on the deck of an aircraft carrier, one of aviation's most difficult maneuvers.
What's even more remarkable is that it will do that not only without a pilot in the cockpit, but without a pilot at all.
The X-47B marks a paradigm shift in warfare, one that is likely to have far-reaching consequences. With the drone's ability to be flown autonomously by onboard computers, it could usher in an era when death and destruction can be dealt by machines operating semi-independently.
Although humans would program an autonomous drone's flight plan and could override its decisions, the prospect of heavily armed aircraft screaming through the skies without direct human control is unnerving to many.
What could possibly go wrong?
Aerial drones now piloted remotely have become a central weapon for the CIA and U.S. military in their campaign against terrorists in the Middle East. The Pentagon has gone from an inventory of a handful of drones before Sept. 11, 2001, to about 7,500 drones, about one-third of all military aircraft.
