The aircraft shown in most exterior views is a Convair 880, a short-lived and rather unpopular type once used by around a dozen airlines. The specific aircraft shown was initially flown by Japan Airlines, and was owned by Century 2000 at the time of the Quincy episode. Subsequently, it was converted to a freighter and flown by Profit Express, Aero American Corporation, and Central American Airways, before being scrapped at Puerto Rico in 1985.
