I'm writing a novelette/novella but I've having some plot issues. This is the synopsis of the story: USSR, 1963, a self-trained pilot and forge worker is given the chance to go into space to fix a top-secret satellite orbiting Earth by the KGB and "Design Bureau". However, due to events from his past (his brothers tried to revolt against the previous government, ending in a fatal riot and leaving the family name stained), he develops an incredibly low self-esteem. Society shuns him and treats with disrespect. Even his girlfriend decides to leave him. He realises he has to change and fully commits to the secret mission, leaving his old life and living in secrecy. He struggles through training and contemplates giving up, but after meeting his hero, he pushes on and exceeds everyones expectations. (I might need to add more sub-plots from here, such as a possible love-interest, a rival pilot who also wants to do the mission, meeting a character from his old life, or the protagonist almost finding out the truth.) The protagonist finally goes into space, but problems occur with his equipment and cannot continue with the mission. However, he discovers that the equipment failure was planned, and tries to comprehend his situation. He decideds to record a message and hide it in either the space capsule or the satellite (which he inadvertently reaches after leaving the capsule). He then submits to his fate and dies in space. There is also an epilogue. So, my issue: does it seem a bit far-fetched that a whole KGB department and "Design Bureau" would convince a civilian to go into space, just to leave him there to die because they believe he was a threat to the government? I mean, there are still current members of the KGB that were in the previous government who would be calling the shots, but would people find this believable? I know the USSR did this (minus the threat to the government) with Laika, the first dog in space, but would people really think they would do this to a human? Also, any more suggestions I could include for a sub-plot for halfway through the story? The ending will stay as it is, though.
