Behind the scenes

 * The transcript for this note is exactly the same as the transcript for the Fort Constantine launch codes appearing in Fallout 3.
 * In reality, the launch codes for America's Minuteman ICBM's were 12 zeros up until the 1970's when the government made the air force provide "real" launch codes.
