ARPANET development was centered around the Request for Comments (RFC) process, still used today for proposing and distributing Internet Protocols and Systems. RFC 1, entitled "Host Software", was written by Steve Crocker from the University of California, Los Angeles, and published on April 7, 1969. These early years were documented in the 1972 film Computer Networks: The Heralds of Resource Sharing.
A press conference on April 14, 1969, gave the design of the LM cabin as the reason for Armstrong's being first; the hatch opened inwards and to the right, making it difficult for the lunar module pilot, on the right-hand side, to exit first.
After a nearly decade-long national effort, the United States won the race to land astronauts on the Moon on July 20, 1969, with the flight of Apollo 11. Nixon spoke with Neil Armstrong and Buzz Aldrin during their moonwalk. He called the conversation "the most historic phone call ever made from the White House"
About 19 minutes after Armstrong's first step, Aldrin joined him on the surface, becoming the second human to walk on the Moon. They began their tasks of investigating how easily a person could operate on the lunar surface. Armstrong unveiled a plaque commemorating the flight, and with Aldrin, planted the flag of the United States.
