Oh man, if the 747-400 has a big cockpit compared to the 777, the 747 must be REALLY small!
I jumpseated a 777 from ATL to MCO a few years ago and I almost had to ask the captain, "Umm, Boeing is kidding, right?"
It was THAT small. I think the 767-300 has a bigger cockpit than the 777 if I'm not mistaken.
