Well, the mission simulator is unlocked by getting all 5 different endings. Electrosphere (with Dision), Geopelia (with Keith), Sole Survivor (with Fiona), Self-awareness (with Cynthia) and A Canopy of Stars (with Erich). As for the super planes, I honestly don't know. People say that if you get an A on all 52 missions you can get them, but I swear that a long time ago I went on a full playthrough of all the missions in the simulator and when I got A in ALL OF THEM, there was still no Night Raven or Aurora or Geopelia. Maybe it doesn't unlock them in mission simulator, but the normal game. I don't know.
