Re: 2 billion in today's market
A lot has changed since the start of manned spaceflight, not just in politics, directly in technology, and more recently the wherewithal and capability of private enterprise. Sure I think lessons can be learned from the past, and hindsight is always 20:20 but comments about the Shuttle program I think are unfair as this was undiscovered country, we really were not capable enough to produce a reusable spaceplane then, for all sorts of reasons. Maybe we still aren't, but I believe we are now getting somewhere. The methods and implementations find their own way and we should continue to look forward and embrace a probable kaleidoscope of orbital transfer vehicles. The first generally affordable car was but a single model, nowadays there are over a thousand different ones to choose from, in about a hundred years. Let's let time progress and watch the future come to us.
