21st Century Jet: The Building of the 777 S01 E05 Countdown to Delivery

Six months prior to delivery to United Airlines, a whole 777 is tested to destruction to measure the force its wings can withstand from turbulence or emergency maneuvers. It flies a mock airline schedule to prove its reliability. A United pilot "test drives" the 777, and United transfers payment of more than 100 million dollars, concluding with the 777's inaugural commercial flight.
