"Microgravity" is irrelevant in this context, it just means the ship is falling. Sure, it's a little bit easier from 68 miles than from 7 miles, but again, that's just the altitude, which is already the easier part. It does nothing to help you gain orbital velocity.

And, rocket engines have not developed that much in 30 years. We are still stuck with the weight-to-energy limitations of chemical reactions.

"Suborbital" is a very different concept from "low earth orbit".

"Suborbital" means you don't have enough speed to stay in orbit. Getting to the required altitude is the easy part of getting into orbit. Once you're there you need to stay there, which takes far more energy to achieve.

SpaceShipTwo is strictly suborbital, as is apparently ASM-135.

That would all make sense if we didn't already know how to get into space.

I don't know if you've notice, but we do. We don't need to take baby steps to get there, we can already go. This isn't a scheme to figure out how to get into space, it's a thrill ride for rich people.

The people who are actually trying to get into space aren't doing anything like this. They are building things that actually go into space.

In order to get a loan you must first prove you don't need it.
