Obama, McCain Campaign Planes Collide - Ohio Still Up For Grabs.

It was bound to happen when you get two candidates, each crisscrossing the country, sometimes twice in one day, headed for campaign stops in nearly every contested state in the Union. Late last night the jets carrying Illinois Senator Barack Obama and Arizona Senator John McCain collided on the runway of an Ohio airport as Senator Obama's plane was taking off and Senator McCain's was going down. Neither candidate was injured in the crash and within minutes both candidates were back on the trail with Mr. Obama leaving the airport in a chartered bus via the high road and Mr. McCain in a cab going by the more familiar and heavily traveled low one.
