Re: "Elon must be grumbling to himself today that he didn't get there first"
I totally agree with Big John.
McDonnell Douglas had already demonstrated vertical takeoff and landing by a rocket some 20 years ago.
It's that order of magnitude greater delta-v and all the challenges that come with it that is the real rocket science.
Not to belittle the New Shepard achievement, but Musk is openly aiming for Mars, Bezos is only aiming for 100 or so klicks up.
