On January 27, 1967, the day of the Apollo 1 fire, Armstrong was in Washington, DC with Cooper, Gordon, Lovell, and Scott Carpenter for the signing of the United Nations Outer Space Treaty. The astronauts chatted with the assembled dignitaries until 18:45, when Carpenter went to the airport, and the others returned to the Georgetown Inn, where they each found messages to phone the Manned Spacecraft Center. During these calls, they learned of the deaths of Gus Grissom, Ed White, and Roger Chaffee in the fire. Armstrong and the group spent the rest of the night drinking scotch and discussing what had happened.
