Boeing's Renton 737 airliner production plant this week rolled out its first 737 aircraft produced at a new record rate of 42 a month.
That plane will be delivered to Air Berlin in about three weeks after it undergoes testing and calibration.
The aircraft will be leased by Air Berlin to Transavia France.
The production rate of 42 monthly is the highest 737 production pace the Renton plant has ever achieved. That rate will be raised to 47 monthly by 2017 to meet the demand for the popular single-aisle airliner.
As recently as 2010, Boeing was building 31.5 737s a month in Renton. That production rate sank as low as 14 monthly after the 9/11 terrorist attacks caused airlines to put aircraft orders on hold.
