NASA video showed debris falling off Discovery. Discovery roared into space today, carrying the first crew to orbit on a U.S. spacecraft since the 2003 Columbia disaster. Commander Eileen Collins described the ascent as her smoothest yet and said: "I couldn't ask for a better flight." But video from the liftoff showed what appeared to be a piece of debris falling off Discovery. www.cnn.com From me Nasa said there is no way to completely keep debris from falling during launch but would look over all the video they have of the launch to make sure no damage was done to the shuttle.
