We commonly refer to the central “object” in extra-galactic radio sources as the “engine” that is the root cause of many radio source characteristics. We frequently ask, COULD “engines” at the cores of extra-galactic sources: (1) be compact objects with accretion disks; (2) eject well-collimated supersonic jets; (3) show relativistic effects in ejected material; (4) produce twin-jets; (5) produce one-sided jets; and (6) initiate highly polarized synchrotron radiation sources? SS433 is a binary star system with radio and optical jets that is relevant because it is a “little engine that could”, and does, do all of these things. Further, we can observe changes in SS433 on time scales from hours to several months, and these data allow one to study evolution of jets in a more thorough fashion than is possible for extra-galactic sources.
