"An ideal chicken in a vacuum", I'm going to remeber that one. It's near my bedtime here, but if we're going to talk science and in view of the recent anniversary, my most startling discovery of the last month was that when the Saturn V lifted off the pad back in July 1969 it took the power equivalent to fifty-five modern diesel railway locomotives just to run the fuel pumps!!!!!
As I've always said "Rocket science isn't that complicated. It's just BIG!)
