Stepping off the lunar landing module Eagle, astronaut Neil Armstrong, became the first human to walk on the surface of the moon and spoke these words.
"That’s one small step for man, one giant leap for mankind.”
There would be five more successful lunar landing missions, and one unplanned lunar swing-by, Apollo 13.
The Apollo program was a costly and labor intensive endeavor, involving an estimated 400,000 engineers, technicians, and scientists, and costing $24 billion (close to $100 billion in today’s dollars).
Reports indicate that some 600 million people watched as Neil Armstrong took the first step on the moon. That televised event set a world record that went unbroken until Prince Charles and Lady Diana married in 1981, which drew 750 million viewers.
