ARLINGTON, Va., Jan. 5 (UPI) -- A small propeller-driven drone has stayed aloft for more than two days and nights, achieving the world duration record for its class.
The U.S. Defense Advanced Research Projects Agency said the flight by the VA001 was conducted in late November and early December at at testing center in New Mexicos and "for nearly 56 hours, the plane flew at an altitude between 6,500 feet and 7,500 feet above sea level, averaging 57 knots before landing on the afternoon of December 2."
