We are taking two relatively mature transportation systems (aircraft, cars) and lining them up against a very immature one (space vehicles). If you take the cars and aircraft in their developmental infancy, they were likely every bit as dangerous and every bit as expensive, relatively speaking.<br /><br />You might even make a case (admitedly weakish) the other way. Namely, that given the relative maturation of the aircraft and car industries, accidents causing death should have been entirely eliminated by now. But, so long as humans are anywhere in the design/manufacturing/testing/operating process, this will be an entirely unrealistic goal.<br /><br />While no death is desirable, I would contend that the Shuttle has done 'well' to only have had fourteen flight deaths during its operational lifetime. spaceiscool has two critical flaws in his logic. Namely that he thinks the next generation space vehicle will be inexpensive to build and operate, and that it won't kill Astronauts. Neither statement is likely to be true. <div class="Discussion_UserSignature"> <p><em><font size="2" color="#ff0000">Who is this superhero?
