There were only a handful of V1 made with a cockpit on it, these were manned by test pilot trying to find out what made them crash just launch. The problem was solved by a woman test pilot
Her name was Hanna Reitsch.
The Fieseler Fi 103R manned missile was one of the many desperate projects conceived as the German situation became more hopeless. Basically the Fi 103R was a piloted version of the V-1 flying bomb powered by the same Argus pulsejet engine.
By mid-1944 preparations had been made for mass production, in time for the operation to attack the Allied forces amassed in southern England. The Fi 103R was to be carried by a parent aircraft and released near the target.
The pilot would then take over and guide the bomb to a dive toward the target, and he was to detach the canopy and bale out just before impact.
The canopy, however, would very likely block the pulsejet inlet and reduce the chance of pilot survival to almost zero. Nevertheless the Germans went to great lengths to distinguish their Selbstopfermänner (self-sacrifice men) from the Japanese Kamikaze pilots, whose cockpits were sealed close before take-off.
The Fi 103R's operation was codenamed Reichenberg and a total of about 175 Fi 103Rs (R for Reichenberg) were made. The R-I, R-II and R-III were used for testing and training, and R-IV was to be the production model.
Two Rechlin test-pilots crashed while flying the Fi 103R; afterwards trial flights were transferred to DFR test-pilots Hanna Reitsch and Heinz Kensche. Flying the Fi 103R was quite simple, since the Fi 103R's unmanned version could fly without direct control.
Landing on the other hand was very difficult due to the primitive control system, absence of landing gear and high landing speed. This should not have mattered much because the Fi 103R was not designed to return anyway!
The project never took off, due to the German high command's apathy, even though some 70 pilots volunteered for training.
