Boeing reported a $1.64 billion loss for the third quarter on Wednesday as it delivered fewer copies of its best-selling plane and sunk more money into building two new Air Force One presidential jets. The aircraft maker lowered its forecast of 737 Max production to between 375 and 400 planes this year, down from a previous estimate of 400 to 450. Boeing said production and deliveries of 737s will be slowed as it does inspections and additional work to fix a pressure-sealing section of the planes.
