Not the upgraded ENGINE. The upgraded ROCKET. See this PDF: http://www.ulalaunch.com/docs/produc...tCardFinal.pdf Note on page 2 "Delta 4 performance and growth options." The upgrades there have lifting power approaching that of the Saturn V. That upgrade. We don't need performance growth. What do we need in deep space that can't be launched in 50,000 lbs. or smaller pieces? The Apollo CSM launched with a light fuel load on a ~40,000 lbs. capacity Saturn IB and the LM was only 33,000 lbs. Brian |

We're heading into trollville here, aren't we? Nope. just hoping desperately, that people would be willing to actually discuss things rather than constructing a strawman and debunking that and then declaring the discussion over. One of the reasons for the decline of these groups is that they slowly devolved into repeating the same slogans, the same dogma, the same groupthink, the same, the same. When that happens - what reason is left to continue? I understand your point, Derek, but I don't think you can say with certainty that the emergency oxygen systems have never saved a life. To say that, we'd really need to run the same disaster scenario twice, once with and once without the oxygen masks. It might be that the masks popping down have saved lives by preventing some folks from having heart attacks during depressurization events. Maybe just by popping out and being reassuring in a silly dangly orange way. Or by giving people something that they believe is purposeful to do during a time of great stress. I do think it is probably fair to say that it is not clear that the emergency oxygen systems on commercial aircraft have ever saved a life during a depressurization event. -- -- |

And we need a placebo group to check this out where the oxygen masks come down but _don't_ deliver oxygen to the passengers. And another group where instead of oxygen masks, live tarantulas descend onto the passenger's faces to see how many heart attacks that would generate in times of extreme stress. Then there are those venomous snakes in the cargo hold to consider. Tell the passengers about those right after takeoff, and note if any have heart attacks right then and there, or if it takes a flight attendant with a rubber snake attached to her throat running screaming through the cabin to get the desired effect. ;-) Pat |

I think it is difficult to make categorical statements about what might have happened differently if supplemental oxygen masks were not depoloyed. The group of people who fly on commercial airlines aren't exactly NASA astronauts. There is a huge crosssection of ages and health issues that are not well sampled by tests performed on 24 year old males in peak physical condition. Craig -- -- |

![]() I think one of the main advantages of the masks would be in a case where there was smoke in the cabin that was causing respiratory distress to the passengers before they had a chance to land and evacuate. Pat Well according to the TV show Air Emergency on national geographic pilots are trained to NOT deploy the emergency oxygen in case of smoke / fire since it will just feed the fire. |
