Many years ago at the bowling alley somehow a discussion of the deterioration of the Ozone layer
occurred. One of the discussion members blamed this on the holes in the atmosphere caused by launching the
space shuttle. His idea was that this poked hole allowed the ozone to escape. After a minute or two, I told him that
this was twice as bad as he thought since the shuttle poked a hole in the atmosphere on the way back to earth.
The look on his face was priceless.
