If a crisis arises during shuttle Discovery's planned return to flight in May, Lindsey and a crew of three could be called upon to lift off aboard sister ship Atlantis on an emergency mission that would be the first in the history of human space exploration. Rescue flights were hotly debated at NASA after shuttle Columbia broke up in the skies above Texas two years ago this Tuesday. Questions arose about whether Columbia's seven astronauts could have been saved. Because of the accident, NASA will have a backup shuttle and rescue crew ready for at least the next two flights in case another ship suffers damage similar to what brought down Columbia."
