As a former HVAC engineering student, I was quite caught by "ozone" in this headline. Sorry, I did not continue with that career for some reason, for good or for bad, now doing an IT job. This ozone thing was talked about almost everyday, not everyday then very often, throughout the four-year study. I think it is a good example of "We did something, so a disaster did not happen". Maybe, also we should learn that we cannot let some people to prove they can create a disaster.
