It's great that we are seeing competition and the video is nice and all. But I wonder how will BE leapfrog the development steps to produce a vehicle almost as capable as Falcon Heavy (45t vs. 50t to LEO) with no prior experience with orbital vehicles ? Development of Falcon 1 started more than a decade ago, SpaceX went through multiple design iterations, test vehicles (Grasshopper) and expensive failures and FH is still maybe a year away, despite being essentially a bundle of Falcons 9 (itself, a very smart strategy to move forward by leveraging their proven capabilities and minimize risk). A large innovative rocket like Glenn might cost a billion dollars to design, build and launch. A billion dollars for an experiment that might fail on the first go. I want to believe Glenn will fly before 2030, but what I would like to see from Bezos is less ego and more roadmap details, a firm monetary commitment from himself or other financiers, etc.
