Interesting documentary about Skylon:

However, I think it underestimates the fundamental problem with Skylon. It’s very clever, but suffers from what you might call ‘Apollo Syndrome’; it’s very much an all or nothing design which needs huge up-front investment with no guarantee of success. Without that multi-billion dollar investment you have nothing of use, which effectively limits it to a government program as few companies can afford to take that kind of risk.

SpaceX, for example, expects to reduce launch costs to Skylon levels when they have a fully-reusable Falcon, but they don’t need to invest vast amounts of money to do because they can make money from the expendable Falcon first and work toward the low-cost reusable design. The best suggestion I’ve seen for Skylon is to use it as a hypersonic airliner, but that still requires doing most of the work and there’s no proven market.

So will it ever fly? I’d like to think so, but I honestly can’t see how they’ll convince the people who have enough money to give it to them.

Neil Armstrong died, but by now you probably know.

As I said elsewhere, the sad part is not just that the first man to walk on the moon has died, but before long we may be in a world where no man alive has walked on the moon. What a huge step backward for the human race.
