Moon Droppings

When Apollo 11 touched down and Neil Armstrong first set foot on the Moon he officially uttered the historical words,

"That's one small step for [a] man, one giant leap for mankind."

So why is the 'a' in brackets? Well it seems he had planned to say for 'a man' but in the excitement he wasn't sure if he had said it. Whatever happened on the day, it still produced a memorable historical quote. Computer scientists have analysed the audio from the momentous day and claim that the 'a' was said but is missing because of problems with the quality of the audio feed. After all the Moon is far away and it was the 1960's. Dropped 'a' or not, the Moon landings were a pinnacle of human scientific achievement and involved some very clever NASA electronic engineers and computer scientists too.
