 In all three Terminator films, the Terminators definition of "being  back" means entering a building by driving a vehicle through it: In  "The Terminator", he drives a car into a police station after  saying, "Ill be back." In "Terminator 2", he drives a SWAT van into  the Cyberdyne Building after saying, "Ill be back." In "Terminator  3", he flies a helicopter into an airplane hangar, steps out and  proclaims, "Im back!"
