 The Federal Aviation Administration has granted Boeing permission to begin a sequence of test flights needed to win approval for the 777X to enter passenger service. Boeing test pilots conducted their first certification flight Friday night with FAA personnel on board the aircraft it took off from Boeing Field just after 6 o'clock and landed there again about two hours later. The Times report it's a major boost for Boeing and should unlock new orders for the aircraft, sales of which have been stalled by long delays in its development and a lack of progress toward getting it certified.
