Space exploration is a daring enterprise - and it is worth the best of our efforts. And the efforts of our best. It is the human quest asking for answers from where we come and where we'll go and what it's all about. The Columbia crew knew there were dangers. It was their personal decision - noone walks this road because of trivial reasons. So we should give our thoughts and prayers to the families who lost a person whose life and dreams they were lucky to share. Keep them in good rememberance. Willy
