At the moment http://www.wikipedia.org/wiki/Challenger_expedition links to http://www.wikipedia.org/wiki/John_Murray . The Murray who has an article was a Cantor-Siegel employee killed in the World Trade Centre, and there is a tribute from his family on that page.
I'm extremely loathe to disturb it, but the Murray who collated the Challenger data will, at some point deserve an article to. Was it decided that there is a repository for the 9/11 tributes, which would be a fitting resting place for the present John Murray article?
