The second 777 off the assembly line at the Everett Assembly facility was used as the test article for the structural integrity of the Boeing 777. A computer-controlled test rig applied one-half millions pounds of force to each wing to test the static load limit (up-bending, down-bending, and asymmetric bending) and validate the structure could withstand more than twice its design-limit load.

The Boeing 777 family is a complete family of jetliners that is preferred by passengers and airlines around the world. The 777 is available in six models: the 777-200, 777-200ER (Extended Range), a larger 777-300, two new longer-range models, the 777-300ER and 777-200LR Worldliner (the world's longest range commercial airplane) and the Boeing 777 Freighter.
