On March 16, 1957, at 8 o'clock in the morning, a 300 ft long spacecraft landed in a field in Alexandria Virginia.

Two local police officers arrived on the scene. The door of the craft slowly opened. The officers drew their guns, not sure what to expect.

To their surprise, out walked a normal-looking guy. He smiled at the stunned officers and actually waved hello.

Before the policemen could say a word, the stranger said, in clear English: "I need to see the president."

Nine months after this event, NASA was founded.

If you don't know this one, hold on tight. We're going on a hell of a ride.
