(edit: replying to anvel's post previous to the one directly above)<br /><br />anvel, I'm not going to try to change your mind, I'm just going on record with rebuttals. Your arguments are old and familiar to me. Using matching paragraphs, 1 thru 5 . . .<br /><br />The comparison is moot. No one travels commercial aviation for any reason than to go somewhere else on the planet. You are correct that the novelty of flying on the Concorde means next to nothing in the marketplace but floating and gazing at the Big Blue Marble means next to everything in space tourism. The claimed lack of affordability does not follow, nor the final sentence.<br /><br />You paint with a broad brush. Not all multi-millionaires are the stay-at-home types. You are not familiar with the target market in this enterprise. The industry will sustain your lethal setbacks, should they occur. NASA has preached since forever how hard it is to do space, the first fatal accident may be a long time coming but if it comes sooner, there is no actual mechanism in place to shut the industry down. Public outrage will not happen. This is not government money here, just regulatory powers.<br /><br />I don't like analysis by analogy, but I am not going to defend ISS here either. I can make a case for ISS but it is not easy and off topic.<br /><br />False analogy and off topic politics. Yes, we face huge financial challenges down the road. That happens to be why I advocate the fastest possible development of space. The faster we get er done, the more space can help us meet these challenges. Space is the next economic boom, it's a matter of when; if soon enough, we build the wealth soon enough to meet these challenges and shrug them off like the great country we are.<br /><br />My predictions can be assumed to be the opposite of yours. <img src="/images/icons/laugh.gif" /> <div class="Discussion_UserSignature"> </div>
