Who knows what spinnoffs will come from this program? Dan, U.S. Air Force, retired I continually bump up against my perceptions of what cheap is, and what other people consider to be cheap. I don't consider the EZ series of airplanes to be cheap. I also feel that they are tiny, don't carry much and are compromised towards the high speed end of flight such that they land at excessively high speed. But that's just me. What spinnoffs might come from the X prize venture Good question, I can't think of any. Corky Scott Remember the "space plane" NASA was working on that would get you from NYC to Tokyo in a couple of hours? I think a spin off might just be the commuter equivillent between Lost Angeles, Peoples' Republic of California and NYC, NY. I know it took about an hour just to get to launch altitude, but SS1 is essentially a proof of concept. Maybe Rutan has a 200 passenger version in the back of his mind. Dan, U.S. Air Force, retired |

No, he real money went into making time slow down when he powered up and defying the normal laws of physics, like pushing a wakk over without tearing the soles out of his shoes or bunding down a light post by pulling on it. And that ear! Still Top Secret technology. -- Charlie Springer The $6 million dollar monkey had the eye, the bionic babe had the ear. I can't believe this thread has devolved into this. OK, I can.

Made me nervous about the cigars I used to smoke after we got airborne with mask open just hanging by strap. Used the flare gun port on left side of cockpit to get the ashes out of cockpit. Just put cigar down near the hole and flick and poof they were gone. Would be interesting to see the specs on cockpit of SS1. Had to have some pressurization and probably used pressure breathing in conjunction to keep pilot awake/alive.

Yes, but I still wonder how anyone in their right might would use a nearly pure oxygen atmosphere in a vehicle full of humans and electrical equipment... Matt The difference is Apollo 1 was flooded with pure O2 where jet fighters push O2 from a LOX converter to a face mask. Big difference. The only electronics in the mask is a microphone. Having said that the electrical systems in Apollo 1 were poorly routed and protected. It was an accident waiting to happen. Dan. U.S. Air Force, retired Mike was wearing a standard military style oxygen mask, so the cockpit had to be pressurized. But what the cabin altitude was is anybody's guess. Rihcard It's all a question of partial pressure. At 29,280 feet, even 100% oxygen is barely capable of keeping a human alive, never mind let them do any type of serious exercise (which is why 8000 meter mountains are so hard). I doubt the cabin was at much higher than 15,000 feet, probably lower than that. Which makes the bird all the more impressive, to me. -- dillon When I was a kid, I thought the angel's name was Hark and the horse's name was Bob. |

At that 29,000' 100% O2 is the same partial pressure as 20% O2 at sea level. Glider pilots reach these altitudes in unpressurized cockpits all the time. The record altitude for a glider is just under 50,000' again with no pressurization. Did you know that Spaceship One is registered as a glider? Bill Daniels |

There was also the Temperfoam that a lot of us are using in our seat cushions, and the emergency blanket I keep in my survival kit (pilots in Alaska are required to carry one). Besides those examples there were probably developments in lightweight insulation applicable to aviation and I'd be be very suprised if the state of the art in storage batteries wasn't advanced by the space program. ---------------------------------------------------- Del Rawlins- Remove _kills_spammers_ to reply via email.
