1977 Convair CV-300 crash
You've got to be kidding! You have some stuff about some guys filming a blob that may or may not have been bigfoot and don't have the October 20, 1977 Convair CV-300 crash! This crash killed 3 members of the band Lynyrd Skynyrd and forever changed the face of American rock music.Trilobitealive (talk) 14:49, 20 October 2012 (UTC)
 * The "Crash" needs more references, making that article ineligible to appear. — howcheng  {chat} 17:52, 20 October 2012 (UTC)
