Thanks Silverfox. I kinda knew about the 777 and the A-300 being a 2 man crew, but I didn't know whether or not the 74-4's and the A330 were.
On airliners.net, when you look at the different cockpit shots of the A-330 and 74-4's, sometimes you see a third seat. Usually in the same position where the SO/FE sits.
