Neil Armstrong remembered

Neil Armstrong was a

humble hero who saw himself as a team player and never capitalized on

his celebrity as the first man to walk on the moon, mourners said Friday, August 31,

outside a private service attended by fellow space pioneers, including his two crew mates on the historic Apollo 11 mission.
