This does not apply to normal people or those suffering from nephritis with high blood pressure...
...Berlin, the Raab-Katzenstein airplane makers hitched a motorless glider to the tail of a regular plane. To the tail of that glider they hitched a second glider. This "train"-the air equivalent of a motor truck with tandem trailers-taxied across the field and managed to take off, the plane tugging, the gliders lunging after. Soon the "train" straightened out in smooth flight and without difficulty attained an altitude...
...Opel told them more about rocketing. The perfecters of the idea were two German inventors named Valier and Sander. They had rocketed a racing car (without a driver) as high as 430 m. p. h., he said. They thought, of course, that they could revolutionize aerial locomotion. In the Raab-Katzenstein works at Cassel, they were completing a rocket-drive airplane, the Grasimiecke ("Garden Warbler"). Only a moderate 125 m. p. h. would be attempted with this craft. Later airplanes would be built to rocket beyond the highest flights of motored airplanes, first with laboratory animals aboard-and plane-parachutes...
