When there is a small number of launces it is difficult to acieve statistical significance you are right. On the grounds of cost the Suttle was twice as expensive per Kg as Ariane which in turn is more expensive than the shuttle. Ariane is 0 for 0 WRT launches vs. disasters. I think we'll need several years to see some sort of track record. By safe I was really meaning safe enough for the ordinary Joe to use. Please explain the ratio of safety regarding astronauts and ordinary Joes. You seem to have some number in mind. And tell me how you arrived at such a number. Actuaries use statistics to calculate safety, risk and by extension, insurance premiums. By your own admission you don't have enough statistics. There will have to be several generations before that is the case. Which no one can guess the timetable of at this point. On cost the basic fact is that so far cost reductions have come by building expendibles cheaper rather than from reusable technolgy. This may change in the future. The main problem is that the pace of developments in rockets is glacial compared with the rate of improvement in payload capability. Using an analogy such as "glacial" in these times of Global Warming is misleading, but I do get your point. It will be interesting to see what Ariane can do. I wish them well. Has ESA selected their first group of astronaunts yet? Eric |

Hay you damn fool, I agree and then some, because for $50K I might be able to deliver a super-deluxe full-blown 100 empg hybrid Hummer at zero NOx to boot, and a fancy enough hybrid GM Volt of 200 empg at under $25K (also at zero NOx). A two seat minimal pod of a zero NOx car should not have any problems with achieving its hybrid 400 empg from each spendy fossil or synfuel gallon as long as it's getting its fair share of h2o2 instead of our polluted atmosphere of mostly N2. I'm talking of a one cycle ICE and also of the h2o2/aluminum battery or fuel cell as the do-everything form of a mostly fluid derived and/ or solid form of stored energy usage that's fully renewable, and even if need be without another drop or gram of anything fossil. - Brad Guth |

I'd expect to see roughly a forth to as much as a third less empg while sustaining an average of 65 mph. |
