Former astronaut Jim Lovell talks about his historic space flight in Cape Canaveral, Florida, April 9, 2010. It's been 40 years since Apollo 13 safely returned to Earth after a oxygen-tank explosion prevented the spacecraft from landing on the moon and put its three-man crew in danger. Four decades later, NASA and the surviving two astronauts, Lovell and Fred Haise, are celebrating an aborted mission that turned potential disaster into a successful recovery.
