I remember watching the documentary series on the design and making of the Boeing 777. I remember seeing this segment on how far the wings actually flexed upwards. But most of all, I remember the genius of dampening the toilet seats so they don&#x27;t bang when let down. They did it because bangs and loud noises scare passengers.<p>If you&#x27;re interested in the documentary, it&#x27;s a 5 part PBS series from the 90&#x27;s. You can find it on Youtube.
