Pat yeah way too big, 2 are all thats needed. but it really doesnt matter, that add on flight isnt going to fly a airliner launched vehicle to release altidude is far better all the support jobs can be in houston and KSC where the airlier takes off from. with release over the equator for maximum weight capacity. but none of this matters either. republicans have promised to slash fed spending. Heck ISS might be on the chopping block |

Actually they pretty much need 3 crew now to do all the checklists and the like. Probably safer with going with at least that number than changing procedures at this point. As for the 4th, again the extra hands probably outweigh the risks. Pat -- Greg Moore Ask me about lily, an RPI based CMC. |

Pat Speaking of Bangladesh, a friend who used to fly for Trans America says that the very mention of Bangladesh makes his skin crawl. He says the best way to see bangladesh is from 30Kft -- preferably higher. The place is inherently doomed for its populace, like Haiti. You look at its history and you think "Isn't there some way we can get the whole population out of there to someplace better? I mean, they certainly didn't deserve this for the bad luck of having been born there." Pat |

Uhm, Pat, loot at the stats of where the highest rainfall is. Any tropical location with a coastline will have the same weather that Florida gets. Rain is one thing; the Amazon basin gets rained on like you wouldn't believe - but major thunderstorms with their high winds, hail, and severe lightning are another thing entirely. Pat |

Jorge on many times has said four is the minimum crew needed for rendezvous flights. Minor note: Atlantis does not have SSPTS, so there will be less time to offload the MPLM. Brian |

The GUCP (Ground Umbilical Carrier Plate) that leaked is part of the External Tank/Launch Pad interface. The External Tank is brand new each mission. The launch pad side was redesigned last year after smaller leaks. All launch pads have GUCPs or something similar. Last time this happened it was due to a misalignment on the ET attachment plate for the GUCP during manufacture. Pat |

If that's the case, and Atlantis gets stuck up there, it's going to be a pain in the rear to get them all back; that's two Soyuz flights mininum, and can the ISS life support system handle ten crew without resorting to the oxygen candles? Pat a better question........ does soyuz have the extra production capacity to quickly produce 2 or more extra vehicles? i wonder too about what would happen if soyuz were suddenly unavailable for some reason? like finding the vehicles at station cant reenter? |

Actually they pretty much need 3 crew now to do all the checklists and the like. You can get a two-person crew back via one Soyuz with a Russian pilot as the third crewmember. When you hit three, you either need two Soyuz flights, or someone is going to have to learn how to operate a Soyuz (or just get stuck on the station as a cosmonaut takes the other two home...and the Russians will send NASA a big bill if that happens, and have a ball playing up the fact that the crappy Shuttle needed the little reliable Soyuz to save its crew's ass). One thing that hasn't been discussed yet is the scenario where the Shuttle makes it into orbit, but is damaged enough that it can't reach the ISS for some reason. Then they would need a rescue Shuttle to go to it and rescue the crew, and that wouldn't be available on a presumed added last mission. It's probably better to get out of this whole little Shuttle experiment with only 14 people dead and 40% of the orbiters lost. Pat |
