STS-400
Added 400 as a cancelled mission. Different the other LON missions, it was rolled out to the launch pad and the crew was on standby. Rillian (talk) 16:24, 24 May 2009 (UTC)

Completed versus Accident
What about listing Challenger and Columbia last missions in a separate category? By definition, the missions were not "Completed". Rillian (talk) 15:59, 24 May 2011 (UTC)
