Well, all those plane flight sims etc. use tilting to simulate Gs and it works fine. A forwards thrust can be perfectly simulated by tilting you backwards, so long as it doesnt go over 1G!
I was in one of those simulators before, and it was a rally car driving sim. You just sat and watched a big screen and were strapped into this bucket seat. It really felt like you were being thrown around in a rally car.
They've also got some mad sound system to supply rocket vibration etc. I went to a dnb night in Southampton once with a 120k sound system. It shock the windows in the buildings 100 metres down the road, and distorted my vision (by resonating my eyeballs) with the bass when I was inside.
If it's anything like that, it'll be loud.
As for looking out the window, I dont think there are any. There's just front windows for the pilots that have shutters. I think they'll open them tonight when they've killed off the insect hazard.
I dunno why, but I am finding it entertaining. I know people are saying its cruel, but I don't think it is that bad. They're getting a load of money (all of them), and they're given training at the real Stars training site and a zero gravity flight at the end anyway. I'm quite into psychology, and I find it interesting how possible it is to make people believe things that are so unbelievable.
