Though he spent time at CalTech, I don't think it is correct to class John Mankins as an academic. Scientist or government official seems more accurate. Keith Henson ( talk) 03:23, 30 November 2018 (UTC) reply

This page contains a large number of unsourced facts-- needs citations. Skepticalgiraffe ( talk) 21:02, 20 December 2018 (UTC) reply

--ok, I think I've found and added citations to most of the statements here. I'm a little dubious about the reliability of the citations, since all of the various bios seem to say the exact same things in the exact same words, so I expect that they were all cut-and-pasted from the same original, but they pass the Wikipedia Reliable Source test, so I am referencing them. Article still needs a lot of work! Skepticalgiraffe ( talk) 22:01, 20 December 2018 (UTC) reply
