Boeing test pilots completed the first flight of the 737 Max 10 airliner, kicking off a type certification process that is expected to take up to 24 months. The new narrowbody, with a range of up to 3,300 nautical miles, has a longer cabin and can carry 12 more passengers than the Max 9. The Max 10's wing was redesigned to incorporate the new model’s levered main landing gear.
