Descriptions and diagrams of various model airplanes used in experiments with solid powder propulsion, in Germany starting in 1927. Diagram of a 'Storch' model airplane. Diagram of "Ente"(Duck) model airplane. An Opel full scale model "Ent" airplane being checked out on a launching rail at an airfield. Fritz von Opel makes adjustments at the rear of the airplane and, assisted by several other men, moves the airplane along the launch ramp and back again. On the side of the plane is written: "Sander AK-1." Photographers take pictures. The first manned test of an Opel "ent" airplane is undertaken by the Research Institute of the RhonRossitten-Gesellschaft (RRG) under the direction of Fritz Stamer. In the first three trials the airplane fails to rise and simply skids along the ground. However, on the 4th try, it successfully flies off the launch rail in an extended high speed flight, for three-quarters of a mile in just under one minute. The successful flight is then shown in slow motion from two different camera angles.
Successful test of the first German Post office mail rocket at Dummersee, Germany, on April 15,1931. It carries 180 pieces of mail (postcards). Reinhold Tiling is seen with his mechanic, Friedrich Kuhr, who holds the rocket, as Tiling inserts a cylinder containing compressed powder fuel. They then invert the rocket and Tiling affixes its nose cone. A post office official hands pieces of mail to Tiling, who places them into the rocket. They position the rocket on its launch stand and fire it. Uniformed Postal officials (and some military officers) watch the rocket as it rises smoothly after launch. Larger, better, and lighter metal (aluminum) are developed in 1931-32. Friedrich Kuhr standing next to a huge rocket with a wing span of 4 meters.

Testing of the "Vierstabers" rockets at the Schwielowsee (lake in State of Brandenburg Germany) by Klaus Riedel and associates, in September, 1933. The rocket set up on its four legs aboard a motor launch in the lake. It launches and flies a short distance to fall into the lake. Another attempt shows a rocket doing the same, except this one explodes upon impact with the water. Scene shifts to October, 1933, with testing of the "Zweistabers" rockets. A motor launch sits in the water, next to a point of land where launch crew is setting up a two-legged rocket.
