I’m with you. If the guidance system reoriented the booster properly the engines and all the ancillary stuff would be heated to well over a thousand degrees. I know SpaceX did a lot of work on how to protect the engines from high temp. And looking at a BE-3, it’s a rats nest of fluid and electronic elements that just screams multiple single point of failure.

Getting a rocket engine up there is one thing, getting it back is another.

Once Blue Origin solves the restart problem, the engines may be reusable. I am not thinking that the restart problem has to do with the design for reusability. It took a couple of tries for SpaceX to figure out their icing problem, as Diane noted, but because so few rockets have landed from space on their engines, there could be plenty of other traps and hazards that engineers have yet to encounter.

I also noticed that liftoff acceleration was very slow. I hope that was due to throttling back engines on first launch. Otherwise, it might not get off the pad with a heavy payload.
