IN FLIGHT - MAY 8:  The bat-shaped B-2 stealth bomber with its flying wing design flies over Whiteman Air Force Base May 8, 2003 near Knob Noster, Missouri.  Whiteman is the home of the B-2's, of which there are only about twenty.  Each B-2 is worth about $2 million USD.  With the Wright Brothers' historic flight celebrating its centennial in 2003, the world is now poised on the threshold of a new age in aviation, one where super-sonic jets refuel in flight, unmanned aerial vehicles track objects with astonishing accuracy, and airliners are maneuvered at times with minimal human participation.  The computer age is about to revolutionize aviation and the United States is unquestionably ahead of the curve in this revolution.  (Photo by Joe McNally/Getty Images)
