The last model created for the Air and Space book, the Jumbo Jet is similar in appearance to the Jet Airliner, but has more efficient use of paper, resulting in fewer steps and a larger finished model.
The Flying Wing, like the Rocket Plane was inspired by some of the experimental aircraft I saw out in Ohio on a trip to the National Air Force Museum after the Centerfold convention. I wasn't satisfied with the original version; the new on is completely redesigned.
