阿姆斯特朗登月时说话的英语原文

Armstrong claims to have said "That's one small step for a man, one giant leap for mankind" when he first set foot on the lunar surface. The "a" is not clear in NASA recordings but the audio and video links back to earth were somewhat intermittent, partly because of storms near Parkes Observatory. More recent digital analysis of the tape by NASA revealed the "a" may have been spoken but obscured by static.
