Former astronaut Jim Lovell talks about his historic space flight for its 40th anniversary 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.
