Raumpatrouille/WMG

After retiring from his adventures...
Mario (de) Monti became prime minister of Italy!

Raumpatrouille and Star Trek are derived from the same future source.
At the end of the Raumpatrouille episode he appeared in, Sciene Fiction author Pieter Paul Ibsen stated that he will from now on only write about the Orion crew. And this is exactly what he did - after attaining access to a Time Travel device and arriving in the 1960s. Here, he pitched the story about an intrepid star ship crew to the Bavaria Atelier GmbH in Germany, as well as to the Desilu Studios in the USA, the latter together with a young author named Gene Roddenberry, who was currently trying to work out the details of his own story concept (called by him Wagon Train to the Stars) when they first met. Of course, any attempt to tell which of both shows will turn out to be the more accurate depiction of humanity's spacefaring future is futile (yet). Perhaps both versions are merely Broad Strokes. But let's make a few assumptions:
 * Cliff Allister McLane (RP), and James Tiberius Kirk (TOS) are based upon the same person.
 * Tamara Jagellovsk (RP), Number One (TOS - The Cage) and T'Pol (ENT) are based upon the same person.
 * Hasso Sigbjörnson (RP) and Montgomery Scott (TOS) are based upon the same person. Scotty's fondness for alcoholic beverages however has been transferred to Mario de Monti in Raumpatrouille.
 * Atan Shubashi (RP) and Hikaru Sulu (TOS) are based upon the same person.
 * Helga Legrelle (RP) and Nyota Uhura (TOS) are based upon the same person.
 * The counterpart of Spock (TOS) is only a minor character in Raumpatrouille, namely Professor Jurko Sherkoff, who only appeared in two episodes.
 * Mura (RP - Die Raumfalle), Elba II (TOS - Whom Gods Destroy) and Tantalus V (TOS - Dagger of the Mind) are based upon the same planet.
 * Pallas (RP- Hüter des Gesetzes), Janus VI (TOS - The Devil in the Dark) and Ardana (TOS - The Cloud Minders) are based upon the same (mining) planet. (In the case of Ardana, this could imply that the Troglytes actually were robots!)
 * The planet Chroma (RP - Kampf um die Sonne) didn't make it into TOS, but as Angel I into an eponymous first season TNG episode.
 * The standard weapon of Earth ships in Raumpatrouille (before the installment of Overkill) is the Lichtwerferbatterie (light thrower battery), while Federation ships in Star Trek have photon torpedoes.
 * The episodes Planet außer Kurs (RP) and The Doomsday Machine (TOS) are based upon the same event. While the Planet Killer in the latter episode never headed towards Earth, the motif of an enormous and seemingly unstoppable object directly threatening our home planet appears several times within the Trek franchise, e.g. in Star Trek the Motion Picture, Star Trek IV the Voyage Home, TNG - "The Best of Both Worlds", Star Trek: Nemesis, ENT - "Countdown", and Star Trek (2009).
 * While where are talking about Planet außer Kurs: The Orion VII dying a fiery death and afterwards being replaced by the Orion VIII, a ship that looks and is named almost identically, is reminiscent to the fate of the Enterprise NCC-1701 (Star Trek III the Search For Spock) and Kirk's subsequent command of the Enterprise NCC-1701-A (Star Trek IV the Voyage Home).
 * The Frogs (RP) are a tough one. They could be the Klingons (TOS), Romulans (TOS), Tholians (TOS), Gorn (TOS), Borg (TNG), Xindi (ENT), or even the Dominion (DS9) . Keep in mind that there is at least one recorded attempt to attack Earth directly (similar to what the Frogs did in RP- Planet außer Kurs and RP - Invasion) for each the Romulans, Borg, Xindi and Dominion.
