Page 210 - At nine in the evening everything was ready. The combustion chamber was ignited and the pressure in it raised to seven atmospheres gage pressure by the old, well-known procedure, by regulating the hand valves for the propellants and water. Just as the combustion chamber had attained this pressure, there was a violent explosion. I immediately closed all the propellant valves and sprang over to Valier, who collapsed. I was just able to catch him as he fell, and laid him on the floor. While a machinist...
Page 58 - Your hopes are founded on the fact that you take certain (in my opirfibn out-dated) astronomical ideas as a basis whereas I am one of the pioneers of Hoerbiger 's glacial cosmogony. " To further push his point and further alienate Oberth, albeit unintentionally, Valier continued, "You understand, professor, what for us, the followers of the theory of glacial cosmogony, the possibility of going in person to the moon, means. This means simply everything! If it is found that the moon is not composed...

He wrote, ". . .we will build such a rocket motor on the ground, on a platform, at our leisure and clamp it down to see how the combustion gases flow through the nozzle .... and (then) we shall put the thing onto a railroad car that is on a straight stretch to track and ignite it .... I then propose that one of these days we put such a rocket motor in a quite ordinary, all-metal airplane. Initially, we take off with the usual engine (then). . . we switch off this motor and let...

Page 58 - ... viewpoint but .a limited appeal to the lay public. He suggested that Oberth convince his publisher that Valier should rewrite the book and bring out a popular version of it. Oberth agreed, but the project was never to be. Oberth simply balked at a sentence in a letter from Valier on February 10: "Your hopes are founded on the fact that you take certain (in my opirfibn out-dated) astronomical ideas as a basis whereas I am one of the pioneers of Hoerbiger 's glacial cosmogony.
Page 67 - ... onto a railroad car that is on a straight stretch to track and ignite it .... I then propose that one of these days we put such a rocket motor in a quite ordinary, all-metal airplane. Initially, we take off with the usual engine (then). . . we switch off this motor and let the rocket function .... The next step is to make an airplane which no longer has the usual engine, but a rocket motor only .... then we will pass progressively from airplane to spaceship. "(4) While Oberth, the theorist, wanted...
