Maybe I'm just weird, but isn't this comet-slinging good practice for obliterating an asteroid which might be threatening the Earth?
It's ten o'clock!
Also could serve as a Billy Bob Thornton, Ben Affleck or Steve Buscemi ejection off the planet Earth device.
That is the only good thing about it that I can possibly think of.
I hope they built two.
Not sure. Asteroids are denser, smaller, and sneak up a lot closer. Anyway, I have to wonder about this stadium-size, 14-storey crater they'r predicting if the impact is successful. In WWII, they ried to dynamite craters in flat icebergs with the thought of making temporary airfields so planes could protect the convoys running to Russia. They couldn't dent the things and gave up on the idea pretty quickly. Since a comet is a big ball of rock and ice...
