I don't usually read this newsgroup so forgive me if this subject has been beat to death previously. I have heard several clains (off the net) that that each shuttle launch has a significant impact on the ozone layer. Can anyone authoritatively address this issue? scott@tripos.com

Can >anyone authoritatively address this issue? > scott@tripos.com There is an article in this month's Aerospace America (May) which illustrates that the harmful effects of 9 shuttle and 6 Titan launches combined is several orders of magnitude less damaging than industrial sources and volcanoes. These data have been presented many times before, however, the cynic would recognize that Thiokol almost always has something to do with the presentation and the answer is always in their best interest.
