<br />Hey here is some more stuff about SS2! Can you believe that re-entry g loading?!<br /><br />http://62.189.48.33/Articles/2006/06/13/Navigation/200/207163/New+SS2+design+details+revealed.html<br />

no, especially for a winged vehicle which doesnot reach orbit

The 7g is probably a peak. Most people can easily handle half of that. And football players routinely survive over 50gs. <div class="Discussion_UserSignature"> </div>

Football players survive very brief 50 G encounters. Around 20 Gs is fatal if sustained longer than a few seconds IIRC. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

What's the black out point?

I find those loads to be very difficult to believe. I still think that even as perceptive an individualt as Rutan still has that Right Stuff kind of thinking about him. Indeed he will probably find at least enough people that can stand this kind of ride in the beginning, but it won't last!<br /><br />For crying out loud the space shuttle has less of a gravity profile that this does!<br /><br />He is going to be trying to get monetarily rich, but physically normal people to try this. Even the 4 g's up is more then the shuttle by 1 g. I would say that he shold reduce that to 3 g's and the trip down at no tmore than 4 g's, maybe 5 g's at most. These people are NOT supposed to be astronauts in the same sense as NASA astronauts.<br /><br />Most teenagers (those that are the greatest riders at theme park roller coaster rides) are not wealthy enough to be able to afford such a thrill ride!<br /><br />Well, it IS going to be at least three years before Virgin Galactic actually starts flying for pure profit, so I guess there will be time to make adjustments. And even afterwords, as they try to bring the price down so as to get more customers I would think that there will also be adjustments!

>>"SS2’s increased down range could enable it to land at Roswell instead of the New Mexico South West Regional Spaceport near Las Cruces, from where it will launch in 2009." <<<br /><br />They may run into local opposition to that. Missile range activities already cause a headache in the region by frequently forcing the closure of U.S. Highway 70 near White Sands. An overflight to the east would probably cause more road closures and other headaches. There is population between White Sands and Roswell, including the Mescalero Apache Reservation and a couple of National Forests, National Monuments, State Parks, and the like.<br /><br /> - Ed Kyle

For tourist purposes they do have to make the flight exciting. Sounds like it'll be fun rather than a ho-hum plane ride that goes higher than usual.

In reply to:<br /><br /> /> />Why would they have to close roads? I don't think they closed of the roads around Mojave when flying SS1. Testing missiles isn't exactly the same thing as flying a routine suborbital spaceflight mission.<<<br /><br />This is a high-speed rocket-powered vehicle that could fly out of control at any point, as SS1 almost did a couple of times. Routine it ain't - at least not yet. (After a few hundred flawless flights, its routine-ness could be revisited perhaps.) An "impact point" will exist beneath its flight path. If it flies in U.S. missile range airspace, it will have to adhere to range safety requirements, etc. If it flies east from White Sands, it will cross two U.S. highways, a railroad, and several towns. <br /><br />BTW, they close US 70 even though the missile launches are not supposed to cross the highway. The closures provide a safety buffer zone on the up-range side of the launch sites.<br /><br /> - Ed Kyle

you must also remember that SS1's uncontrollable moments were when it was at high altitude due to the lack of air over its control surfaces and I believe when its up at 60 miles it used gas jets to control roll. So when it gets back into the atmosphere more it will regain the control. But yes it could go into a spin stall or something just like any other plane can. The feather tail not only slows them down but it also helps control.<br /><br />I don't see the need to close highways for this thing... <div class="Discussion_UserSignature"> </div>
