Fieseler Fi 103R Reichenberg
The Fieseler Fi 103R, code-named Reichenberg, was a late-World War II German manned version of the V-1 flying bomb (more correctly known as the Fieseler Fi 103) produced for attacks in which the pilot was likely to be killed, or at best to parachute down at the attack site, which were to be carried out by the "Leonidas Squadron", Group V of the Luftwaffe's Kampfgeschwader 200.
