nomination for good article status on hold the article could use more images considering its length and subject matter a map would help to tie in the list of team members aside from some minor grammatical fixes the lead section needs expansion and improvement essentially it should be a brief version of the article itself so try to mention the teams some specific experiments explorations roald amundsen etc too this also applies to factors contributing to the failure which should be mentioned rather than referred to another article otherwise the article is very close so i'm putting this on hold
