Re: Still have the book
The wing deformation test on the first prototype was both spectacular and reassuring. They clamped the undercarriage down, then put a hydraulic jack under one wing tip. The wing was at around 45 degrees to the horizontal before it finally failed.
It was also reassuring to know that the 777 could fly for a couple of hours on a single engine, especially when my wife and I were on a Chicago to London flight that was suddenly diverted to Bangor, Maine after the captain had to shut down one engine. Having seen the documentary, we weren't in the least worried about making a safe landing.
