Safire prepared a speech called "In Event of Moon Disaster" for President Nixon to deliver on television if the Apollo 11 astronauts were stranded on the Moon. According to the plans, Mission Control would "close down communications" with the LEM and a clergyman would have commended their souls to "the deepest of the deep" in a public ritual likened to burial at sea. Presidential telephone calls to the astronauts' wives were also planned. The speech originated in a memo from Safire to Nixon's chief of staff H. R. Haldeman in which Safire suggested a protocol the administration might follow in reaction to such a disaster. The last line of the prepared text contained an allusion to Rupert Brooke's First World War poem "The Soldier". In a 2013 piece for "Foreign Policy" magazine, Joshua Keating included the speech as one of six entries in a list of "The Greatest Doomsday Speeches Never Made."
