Michael Collins, seems to be just another name, and he isn't very well known, but be is very important in the Lunar Landing of 1969. He was the third person on the misson. While his two co-pilots went onto the surface of the moon, he stayed on the ship. This man is the loneliest man ever to exsist. He orbitted the moon by himself. Each orbit was two hours long and for 48 of those minutes, he was completly cut off from the world, he could not see it and he had no communication with it. He was the farthest a human can go from another person.
