3-View Drawings
Yes, the plane is made by Boeing, the 707 model, a very early jet. Are you planning to use any digital plans, with a CAD program? I have been able to find a 707 drawn in CAD to manipulate in Design CAD. Janes' Aircraft from a library is one of the best sources of aircraft info, or any book about airliners will also have information. Boeing's site has drawings, but don't know how useful they'll be.
I don't have the 707 in CAD, but if I come across it, I'll let you know.
