Recorded sources
7 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Neil Armstrong said 'one small step' on the Moon?

Yes. Two reference works state directly that Armstrong said 'one small step' as he stepped onto the lunar surface, and several other sources treat the remark as delivered on the Moon while debating only whether he said the article 'a'.
