Why would it not be feasible? the requirements for the effect desired are identical for both round earth and flat earth. You rocket above the atmosphere, then fall back into it. What's so unfeasable about that?
It is possible but in the long run a simulation will be much cheaper. Also, the logical progression from sub-orbital flights is orbital flights. For this reason it is more prudent to perfect simulation technology early on, keeping the orbital experience consistent with the sub-orbital experience.
How much cheaper exactly?
Actually, the next proposed step is site to site transportation. It's expected that Spaceship 3 will be able to fly from London to Sydney in 2 hours. Try faking that.
No. Experience in the pharmaceutical industry. Experienced drug makers.
Knowing how to make a drug is no substitute for experience of taking the drug.
How can you make a drug without knowing what its effects are?
You've never studied aircraft design, have you? Form absolutely follows function when the form is integral to the function. Remember that Spaceship Two must be able to fly within the atmosphere.
How is this relevent?
Remember that 'Spaceship Two' will never leave the ground.
So they have a decoy plane. How much more money would they really need to spend to put a real rocket in it and have people fly in it. If people with binoculars and telescopes will be watching it launch from the ground, they're going to have to have something that launches, engages a rocket, disengage rocket, drift for a bit, reenter, and land safely. Why not have people actually in it?
