If someone has a collection of answers to these questions, please e-mail 'em and earn my gratitude! I heard the other day that each shuttle launch releases an enormous quantity of ozone-destroying gasses into the upper atmosphere, and according to one (believable?) study, the current flight schedule will cause 10% of the pro- jected ozone depletion in the next 5 (or 10?) years. Anyone know the facts about what the shuttle dumps out in a typical flight? Is anyone concerned about the impact of these discharges? Is there an alternative fuel that would have less environmental impact without requiring a major redisign? Realistic- ally, will these issues even be considered by NASA? ------------------------------------------------------------------------------- Eric Mendelsohn When all is said and done, Internet: esm1@midway.uchicago.edu More is said than done.
