Space Shuttle landing track over Columbus

Space Shuttle Discovery was scheduled to land this morning at 8:48 am EDT, but that landing and the next opportunity today were both canceled due to cloudy conditions over Florida's Kennedy Space Center. The landing has been rescheduled for tomorrow (Tuesday) morning at 7:33 am, with a backup time at 9:08 am. (If the weather continues to be troublesome, the landing may be diverted to a site in California).

From Columbus, the first pass will be near the horizon; the second pass will be higher up in the sky. Chances for an actual sighting are extremely low, but there's a possibility of hearing a sonic boom as the shuttle passes over shortly before its landing time.
