I dont think I've ever seen so many people so happy about a destruction test

I thought it was at 154, 154, 154, 154, 154, 154, 154, 154...Twas an impressive test for sure. The rigging alone was worth the watch. Bet they set some standards with that testing! Was curios if this was on a new wing or one with a thousand hours on it or mechanically simulated hours.

Had a couple of flights in 777, one across country in a wing window seat and you could see the wing flex on final approach. Sure am glad those Boeing engineers are On IT!

Is that a yellow rubber ducky on the rigging at the end of the wing?

It has that appearance at 0:27 sossol, but the resolution is not good. There is another shot of it at 2:46 on the floor after the break. I wouldn't put it past the testing crew. Good catch and thought though!

The Boeing 777 program (known then as "7J7") was the BEST large airplane program ever. I worked at a major supplier to Boeing designing components that would ultimately fly on that production aircraft. In those days Boeing was lead by people who were passionate about aviation, although I'm not too sure about the current breed. As a side note, the Boeing Board of Directors should have given control of the company to Alan Mullaly, but he was passed over twice, so he instead went on to become Ford Motors CEO, which thrived under his leadership and business acumen through their difficult years.
