Two images by Dr. Lieberman show debris from the space shuttle Columbia streaking across the sky over Tyler, Texas, Saturday, Feb. 1, 2003. Amateur photographer Dr. Scott Lieberman shot a series of photos showing the break-up of the space shuttle from his backyard in Tyler early Saturday. Space shuttle Columbia broke apart in flames 200,000 feet over Texas on Saturday, killing all seven astronauts just minutes before they were to glide to a landing in Florida.
