Boeing 747-8 Freighter achieves initial airworthiness milestone

Boeing has completed initial airworthiness testing on the 747-8 Freighter. This milestone enables test engineers to be on board during future flights and allows the remaining two 747-8 Freighter test airplanes to begin flight test. Since the first flight in early February, the program has conducted 13 flights, achieving several key accomplishments. Pilots have taken the airplane to an altitude of 30,000 feet (9,144 m) and a speed of Mach .65. The program has completed approximately 33 hours of flying. Initial stall tests and other dynamic maneuvers have been run, as well as an extensive checkout of the airplane’s systems. Five different pilots have flown the newest Boeing freighter.
