 When shown on the BBC, the series was initially run with the first two  episodes edited together. This meant that the opening titles were changed to  account for two directors and two different writers. The Veterans interviews  for Episode 2 (Day of Days) were moved to the end of the episode before the  end credits. In the programme itself, the scene with Winters sitting in the  doorway gazing out at the air armada flying into Normandy is smoothly blended  into the flying clouds sequence that begins Episode 2 (which is much  shorter).
