SpaceX Merlin 1C completed its first full duration firing in 2007, a decade ago. Blue Origin is trying to go straight to a large engine with more than twice the thrust of the Merlin 1 AND using a fuel that has never been used in rocketry for an engine this size. I'm impressed that Blue Origin has come this far, but they are most likely 5 years behind SpaceX, and probably more.
