Dean Pelton decides that Greendale Community College must have its own flight simulator and cannot be bested by the competition, "City College," which is planning its own flight simulator. He enlists the study group to clean and refurbish the Greendale Community College simulator. As Jeff, Pierce, Britta, Annie, Shirley and Troy wash the tattered simulator down, they end up accidentally launching it - sending everyone on an unexpected journey into "outer space." Abed is left behind to try and navigate a safe "return" for everyone.
