The point is the same point that Edmund Hillary and his small civilian band had when they climbed Everest. Sure, Patton's Third Army could have done it by sheer muscle power and expensive engineering, but Hillary did it with finesse. snip Well, no. The 1953 expedition did it along military logistic lines, as did the earlier Himalayan expeditions to the great peaks. The leader of the expedition was Brigadier Hunt, and the planning required to move supplies and people up the mountain was analogous to supplying a 6-8 week military campaign, with Sherpas acting as porters. After it was done that way well into the '70s, smaller, lighter weight expeditions started to try and climb Everest and other big Himalayan peaks 'alpine-style', i.e. the climbers themselves carried all their food and gear with them and climbed in a more or less continuous push from bottom to top. Alpine-style is quicker, lighter, faster, and cheaper (one Japanese expedition in the '70s employed over 700 porters getting their gear to base camp, with a couple of hundred on the mountain itself). Increased knowledge of extreme altitudes and improved technique and equipment made such climbs possible. Perhaps the ultimate in finesse and style on Everest was set by Reinhold Messner's solo climb without oxygen via the North Ridge in the early '80s. He did have a little support; his girlfriend went to his base camp with him, and waited for him there. OTOH, even he was mostly climbing a known route. However, except for the last several hundred yards, so were Hillary and Tenzing, as Tenzing had been to around the South Summit @ 28,700 ft. (IIRR; possibly they didn't get that high) the year before with (IIRC) Raymond Lambert, as part of the Swiss expedition. Bourdillon and Evans had certainly gotten to the South Summit before retreating, a few days before Hillary and Tenzing made the second attempt that went the rest of the way. The 'tourist' climbs of the South Col route nowadays are done in the old style, because most of the people involved lack the climbing skills and conditioning to do it on their own. Expert climbers do old or new routes alpine style. Guy |

ink.net The X-Prize competition is a race to be the "first" to do something that's been done before. What non-government entity has reached outer space (sub-orbital or not)? That's the largest part of the "not been there nor done that" aspect. The two-week turnaround is part of the attempt to demonstrate a viable reusable craft which would encourage commercialization of the activity. The goal of the X-Prize, as I understand it, is to promote commercial access to and use of space with a focus on space tourism. There are private launch facilities, but none of them are for manned spacecraft. All manned space flight is performed by government agencies that many consider to be far more wasteful than a commercial enterprise would be. -- John T http://tknowlogy.com/TknoFlyer http://www.pocketgear.com/products_s...veloperid=4415 ____________________ |

Why is civilian suborbital flight a significant milestone?
That question was answered earlier in the thread. And by the way, "ensure" means to make certain. "insure" means to (promise to) make reparations, and "assure" means to make confident. Jose -- (for Email, make the obvious changes in my address) |

![]() "Chad Irby" wrote in message om... A suborbital flight, and repeat it with the same vehicle in a 14 day period? Funny, I can't remember hearing of such a thing. The capability was there. Individual X-15s were flown within two week periods a number of times and the craft was flown above 100 km. I think you don't understand the actual rules or intent of the Ansari X-Prize. You'd be wrong abut that. |

The X-15 carried one guy (the rules for the X-Prize require that the craft has to be able to carry three, although it only has to have the equivalent ballast for the actual prize flight). The two semi-qualifying (100 km+) X-15 flights took place over a month apart, in the #3 airframe. -- cirby at cfl.rr.com Remember: Objects in rearview mirror may be hallucinations.

Individual X-15s were flown within two week periods a number of times and the craft was flown above 100 km. So now it's not "it's already been done," it's "it *could* have been already done?" I think it's time to give up. The X-15 was a really cool plane, but it wouldn't qualify for the X-Prize even if it was operational today. It couldn't carry passengers. It's a shame the orbital followons weren't funded, or space travel would have looked very different for the last forty years. Mike Beede |

"Steven P. McNicoll" wrote: The X-15 had turnaround times less than two weeks. It did, after some lower and slower flights. Not after the high-altitude flights, though, and the average gap between "hard" flights of the same airframes was a month and a half. They also had a tendency to need major parts of the airframe (tail and wing surfaces) replaced or refurbished after the more demanding flights. Not to mention they were doing this with a much smaller payload. -- cirby at cfl.rr.com Remember: Objects in rearview mirror may be hallucinations. Slam on brakes accordingly. |

McNicoll" wrote in message ink.net... "C J Campbell" wrote in message ... Somebody step on your tail? It really is going to be tough. If Rutan were attempting something easy, it wouldn't be worth all that attention, would it? What, are you trying to belittle his accomplishments or what he is trying to do? Just what is the point of the whole X-Prize competition anyway? I understand the requirements, but why do it all? The Rutan Voyager flight wasn't particularly useful either, but it was something that hadn't been done before. Someone might have said the same thing to the Wrights. The idea is to prove that privately financed space travel is both feasible and reasonable. No government has managed to do what Rutan and the others are attempting. The prize has the additional advantage of attracting media attention so that, once it has been won, public interest in space tourism will be generated.] end snip If you're going to participate you need to learn to retain the responses you receive in a thread. What is outlined above not only demonstrates the significance of the X-Prize, but is also significant in demonstrating that you should be PLONK'ed by everyone in this forum! I volunteer to lead the way. See ya. z |
