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.

April, 1931 in Germany. View of a closed sled resembling a small airplane fuselage, fitted with runners underneath and bundles of rockets on each side. It sits on a frozen lake. BR-1 is painted on its side. A man arrives and climbs into the cockpit. The rockets ignite and accelerate the plane somewhat erratically, as it moves along the lake surface.
First test of a precursor to the Mirak rocket in Germany. Diagram of the so-called Achenstaber rocket.. Rocket pioneer, Klaus Riedel, and an associate, hold the long slender rocket.
