I have found a great documentary on the making of the Boeing 777 (if you're going to watch it prepare some time - it's 5 hours long!!!).
21st Century Jet - Making the Boeing 777 (Part 1 of 5)
Now I have a question not really related, but as I was watching, I heard Jim McWha (the Chief Engineer, Flight Control) speaking (at 31 "10). Does anyone know where his accent is from and why it sounds so familiar?
Otherwise I really recommend watching this - it's a fascinating insight into the development of a new plane and into the inner workings of Boeing. Great
PR on their part by allowing it to be filmed and released.
