Asteroid - Near Miss?

I just read that next week, an asteroid the size of two football fields will just pass the Earth.

"No chance of impact"

These are the same guys who didn't change the metric to English when making a space probe to Mars and missed their target by half a million miles.

This sucker is supposed to be 334,000 miles away from us - or 1.4 the distance from the Moon. Do you have any idea how big "Space" is? That's not a near miss - that's a near HIT. Shouldn't we be sending Bruce Willis and Aerosmith up there to take care of stuff like this? Maybe the guy with the highest score on Asteroids should lead the mission? He's probably got more experience than anyone else on the planet.

So - if in the middle of the night there's a really loud 'bang' kill all the astronomers first.
