 The closing narration states that Gordon Cooper (qv) was "the last  American ever to go into space alone". While true when the film was  made, Mike Melvill (qv) in June and September 2004 and  Brian Binnie (qv) in October 2004 went into space alone in Scaled  Composites SpaceShipOne. Binnies flight coincidentally was the day  Gordon Cooper died.
