We want to learn how to make flying vehicles like this. Meet Luigi Prina, the 83-Year-Old Builder of Flying Model Ships, in this fascinating video profile: The Ships That Sail Through The Clouds

The flying ships are made from ultrathin paper and balsa wood. Everything is optimized for flight: from the weight (between 20 and 50 grams) to the aerodynamic shape. They fly like any propeller airplane. The only difference is that here the propeller is powered by an internal elastic band and not an engine.
