Would it matter if it were as flat and thin as a football field?

These may be facts after a fashion but they are really no more than statistical probabilities. It's just as much a fact to state that a football field could hit us today and another football field could hit us tomorrow. Return period-style facts are not very illuminating, frankly. I live in hope that no football field will strike before the end of Liverpool's game at Anfield tonight. Well, at least as it doesn't hit Anfield. I wouldn't object if it struck Old Trafford as long as the stadium was empty at the time. Even I'm not that nasty to the poor unfortunates who call themselves "United fans."
