Thank you for taking your time to read my post. I do appreciate.

Are you advocating inter-continental travels by rockets?

Yes, I do. I agree that any new technology comes with its challenges, and also understand your concerns on how wasteful rocket engine is concerning energy. But, you will agree that Intercontinental travel by rocket would create a niche market considering the time factor as shown on the post. Concorde once had that niche market for transatlantic (London - JFK) and had challenges doing intercontinental which I believe was one the most significant limitation
