> we've had 4 spills in the gulf, two of which are major And yet "we" are completely unprepared for oil spills, needing months to recover from worst-case scenarios (and decades if not centuries to recover from the long-term damage). That isn't "progressive". > we've had 132 space shuttle launches, 2 of which killed everyone on board It is hard for me to see in how far these incidents are comparable. The damage of space shuttle launches was local to the "experimental room" and was under control in the sense that "just" the shuttles were destroyed and nothing else. The crews were informed about the risk of that experiment and accepted to take the risk.
