The aircraft reached an altitude of 5,000 feet during the four hour flight on January 11 at Edwards Air Force Base (EAFB) in California. Both the endurance and the altitude of the system will be expanded in further test flights in order to achieve the planned operational altitude of 55,000 to 65,000 feet."
Comparing information and knowledge is like asking whether the fatness of a
pig is more or less green than the designated hitter rule."
