There have a few reports recently about allegations that some Space Shuttle astronauts weren't 100% sober when they launched. If they had been drinking, is it any wonder?

Senator John Glenn - the first American to orbit the Earth - was once asked how he felt as he sat on the launch pad waiting for lift-off. He replied:
'I felt as good as anyone would, sitting in a capsule on top of a rocket that were both built by the lowest bidder.'
