I downloaded the instructions and history papers. Thank you Mr. Rose, not only for the model but the history lesson, too, Very impressive amount of research. I probably won't build the full size model, first because I don't have a fireplace, and two, my wife wouldn't let me build a 4 foot ISS, so I don't see her approving a 6' airplane. I may one day drop it down to 1:48 or 1:32 and make it for my office. But to everyone, whether you plan to build the model or not, you should load the instructions and history page, it's an excellent read!!
