    Using the rocket equation you can show the payload of the BFS as an SSTO using altitude compensating nozzles can be improved from ca. 1 ton to ca. 20 tons(!)

    The task of getting passengers to orbit for the Mars flight, or for the point-to-point transport role can be accomplished without the large, expensive first stage booster.

    Methods of accomplishing the altitude compensation by just attachments to
    the Raptors are discussed, from nozzle extensions to variations on the aerospike:

    SpaceX BFS can be SSTO with altitude compensation. https://exoscientist.blogspot.com/2019/01/spacex-bfs-can-be-ssto-with-altitude.html

    ------------------------------------------------------------------ Single-stage-to-orbit was already shown possible 50 years ago
    with the Titan II first stage.
    In fact, contrary to popular belief SSTO's are actually easy.
    Just use the most efficient engines and stages at the same time,
    and the result will automatically be SSTO.
