 - August 29, 2008, 1:16 PM

Boeing plans to expand the flight envelope of its unmanned vertical aerial vehicle A160T Hummingbird from the Southern California Logistics Airport in Victorville. The A160T set a world endurance record earlier this year, flying for 18.7 hours before landing with two hours of fuel remaining. Test plans call for the Hummingbird eventually to reach an altitude of 30,000 feet. It has already hovered at 16,700 feet for more than seven minutes and reached a top speed of 142 knots.
