If he has bad luck then he got stuck between the "tunnel of the docking bay" and the rest of the prison building. Like it is when you get stuck in Kyoto Base (Chugoku), or Bruchsal base (Frankfurt). no way to fly to the docking bay "within" the station.Got stuck such a way myself and was only lucky that I had that mean mines to kill myself. No player nor NPC's outside could even hit me.
