—Excerpt from In Event of Moon Disaster by William Safire, a speech prepared for President Nixon to read in the event that Apollo 11 astronauts Neil Armstrong and Buzz Aldrin were stranded on the Moon.
Michael Stevens read this excerpt in this episode of Vsauce (relevant section starts at 9:24) and, I don't know. I just started feeling really emotional about a hypothetical event that, thankfully, never happened, and I wanted to share it.
ETA: Ooooh, only just now, months later, recognizing the reference to Rupert Brooke's The Soldier: "If I should die, think only this of me; / That there's some corner of a foreign field / That is for ever England." Well played Safire, well played.
