First On The Moon : A Voyage with Neil Armstrong, Michael Collins, Edwin E Aldrin, Jr. (1970) edited by Gene Farmer and Dora Jane Hamblin, p. 113, states of this: "Like many a quote which gets printed once and therefore enshrined in the libraries of all newspapers and magazines, this particular one was erroneous.
