Experiments with rocket aircraft

During 1936, von Braun's rocketry team working at Kummersdorf investigated installing liquid-fuelled rockets in aircraft. Ernst Heinkel enthusiastically supported their efforts, supplying a He 72 and later two He 112s for the experiments. Late in 1936, Erich Warsitz was seconded by the RLM to Wernher von Braun and Ernst Heinkel, because he had been recognized as one of the most experienced test-pilots of the time, and because he also had an extraordinary fund of technical knowledge.^[30]^:30 After von Braun familiarized Warsitz with a test-stand run, showing him the corresponding apparatus in the aircraft, he asked:

“Are you with us and will you test the rocket in the air? Then, Warsitz, you will be a famous man. And later we will fly to the moon – with you at the helm!”^[30]^:35

A regular He 112

In June 1937, at Neuhardenberg (a large field about 70 km (43 mi) east of Berlin, listed as a reserve airfield in the event of war), one of these latter aircraft was flown with its piston engine shut down during flight by test pilot Erich Warsitz, at which time it was propelled by von Braun’s rocket power alone. Despite the wheels-up landing and having the fuselage on fire, it proved to official circles that an aircraft could be flown satisfactorily with a back-thrust system through the rear.^[30]^:51

At the same time, Hellmuth Walter's experiments into hydrogen peroxide-based rockets were leading towards light and simple rockets that appeared well-suited for aircraft installation. Also the firm of Hellmuth Walter at Kiel had been commissioned by the RLM to build a rocket engine for the He 112, so there were two different new rocket motor designs at Neuhardenberg: whereas von Braun’s engines were powered by alcohol and liquid oxygen, Walter engines had hydrogen peroxide and calcium permanganate as a catalyst. Von Braun’s engines used direct combustion and created fire, the Walter devices used hot vapours from a chemical reaction, but both created thrust and provided high speed.^[30]^:41 The subsequent flights with the He 112 used the Walter-rocket instead of von Braun's; it was more reliable, simpler to operate and the dangers to test-pilot Erich Warsitz and machine were less.^[30]^:55

Slave labor

SS General Hans Kammler, who as an engineer had constructed several concentration camps, including Auschwitz, had a reputation for brutality and had originated the idea of using concentration camp prisoners as slave laborers in the rocket program. Arthur Rudolph, chief engineer of the V-2 rocket factory at Peenemünde, endorsed this idea in April 1943 when a labor shortage developed. More people died building the V-2 rockets than were killed by it as a weapon.^[31] Von Braun admitted visiting the plant at Mittelwerk on many occasions, and called conditions at the plant "repulsive," but claimed never to have witnessed any deaths or beatings, although it had become clear to him by 1944 that deaths had occurred.^[32] He denied ever having visited the Mittelbau-Dora concentration camp itself, where 20,000 died from illness, beatings, hangings and intolerable working conditions.^[33]

In Wernher von Braun: Crusader for Space, numerous statements by von Braun show he was aware of the conditions but felt completely unable to change them. A friend quotes von Braun speaking of a visit to Mittelwerk:

It is hellish. My spontaneous reaction was to talk to one of the SS guards, only to be told with unmistakable harshness that I should mind my own business, or find myself in the same striped fatigues!... I realized that any attempt of reasoning on humane grounds would be utterly futile.^[34]

When asked if von Braun could have protested against the brutal treatment of the slave laborers, von Braun team member Konrad Dannenberg told The Huntsville Times, "If he had done it, in my opinion, he would have been shot on the spot."^[35]

Others claim von Braun engaged in brutal treatment or approved of it. Guy Morand, a French resistance fighter who was a prisoner in Dora, testified in 1995 that after an apparent sabotage attempt that von Braun ordered a prisoner to be flogged,^[36] while Robert Cazabonne, another French prisoner claimed von Braun stood by as prisoners were hanged by chains suspended by cranes.^[37] However, these accounts may have been a case of mistaken identity.^[38...OP+

Dr. Wernher von Braun First Center Director, July 1, 1960 - Jan. 27, 1970

Wernher von Braun (1912–1977) was one of the most important rocket developers and champions of space exploration during the period between the 1930s and the 1970s. As a youth he became enamored with the possibilities of space exploration by reading the science fiction of Jules Verne and H.G. Wells, and from the science fact writings of Hermann Oberth, whose 1923 classic study, Die Rakete zu den Planetenräumen (By Rocket to Space), prompted young von Braun to master calculus and trigonometry so he could understand the physics of rocketry. From his teenage years, von Braun had held a keen interest in space flight, becoming involved in the German rocket society, Verein fur Raumschiffarht (VfR), as early as 1929. As a means of furthering his desire to build large and capable rockets, in 1932 he went to work for the German army to develop ballistic missiles. While engaged in this work, von Braun received a Ph.D. in physics on July 27, 1934. Von Braun is well known as the leader of what has been called the “rocket team” which developed the V–2 ballistic missile for the Nazis during World War II. The V–2s were manufactured at a forced labor factory called Mittelwerk. Scholars are still reassessing his role in these controversial activities. Click for details. Picture of Werner von Braun suiting up prior to entering Marshall's neutral buoyancy tank in 1967.The brainchild of von Braun’s rocket team operating at a secret laboratory at Peenemünde on the Baltic coast, the V–2 rocket was the immediate antecedent of those used in space exploration programs in the United States and the Soviet Union. A liquid propellant missile extending some 46 feet in length and weighing 27,000 pounds, the V-2 flew at speeds in excess of 3,500 miles per hour and delivered a 2,200-pound warhead to a target 500 miles away. First flown in October 1942, it was employed against targets in Europe beginning in September 1944. By the beginning of 1945, it was obvious to von Braun that Germany would not achieve victory against the Allies, and he began planning for the postwar era. Before the Allied capture of the V–2 rocket complex, von Braun engineered the surrender of 500 of his top rocket scientists, along with plans and test vehicles, to the Americans. For fifteen years after World War II, von Braun worked with the U.S. Army in the development of ballistic missiles. As part of a military operation called Project Paperclip, he and his rocket team were scooped up from defeated Germany and sent to America where they were installed at Fort Bliss, Texas. There they worked on rockets for the U.S. Army, launching them at White Sands Proving Ground, New Mexico. In 1950 von Braun’s team moved to the Redstone Arsenal near Huntsville, Ala., where they built the Army’s Jupiter ballistic missile. In 1960, his rocket development center transferred from the Army to the newly established NASA and received a mandate to build the giant Saturn rockets. Accordingly, von Braun became director of NASA’s Marshall Space Flight Center and the chief architect of the Saturn V launch vehicle, the superbooster that would propel Americans to the Moon. Von Braun also became one of the most prominent spokesmen of space exploration in the United States during the 1950s. In 1970, NASA leadership asked von Braun to move to Washington, D.C., to head up the strategic planning effort for the agency. He left his home in Huntsville, Ala., but in 1972 he decided to retire from NASA and work for Fairchild Industries of Germantown, Md. He died in Alexandria, Va., on June 16, 1977.
