Congratulations to the SpaceShipOne team for a splendid achievement!
To answer some of the points made here, though:
I don't think comparisons with the Space Shuttle are valid. One is a vehicle intended to carry three people to the beginning of space, the other is a more complex vehicle designed to carry seven people plus a large cargo into orbit.
I shouldn't think many people took one look at the Wright Flyer and thought "airliner". However, two years and a bit of development later, some people thought "bomber" instead. After WW1, when there were some big, solid aircraft around, that's when people thought "airliner". Fortunately it looks as though we won't need WW3 to do the same for space travel.
There are a few reasons why space launches aren't practical from the UK. One is the density of air traffic. The other is the
North Sea and all the oil rigs there, which are right in the target area if anything goes wrong...
I hope private space travel won't be brought to a halt when, not if, one of the spacecraft goes wrong and people are killed. This
will happen one day - trains crash, aircraft go down, I see no reason why spacecraft will be uniqely accident-free. And during the early period, when tickets are so expensive, the passengers and their next of kin are going to be the sort of people who can hire expensive lawyers...
Having said that, I hope it does succeed. And if the ticket price falls to something which I can afford, sign me up for one!
