My first self employed stint we made sales filmstrips in Artesia, set up shop in a metal shed owned by a dairy supply. In a loft area, they had many forms and templates made of plywood that were purchased from the Hughes scrap yard. Many were used to build the Goose. I used to be on display in Long Beach, CA, not too far. It was overwhelmingly huge and when you walked up to it, it seemed even more massive. The Cargo hold was really big. The wings were so thick you could walk standing up, if you were short, inside them.
The flight deck was also expansive, and it was amazing to think that thing could get off the ground--or water since it was a sea plane. I doubt you could have had it land on tires, the impact would have been tremendous. The engines were several stories off the ground and were radial. I think they used the standard double rank radial that put out 2800hp each. 8 engines x 2800 = 22,000 hp! I encountered the jigs in the late 60s, so they were about 25-30 years old by then. No delamination was noticeable then. I wonder where those jigs are now?
Hughes invented special hydraulic systems to move the control surfaces.
The more I do, the less I accomplish.
