The first episode of the sixteenth season, shot in June 2008 and scheduled to air in early September, revolved around a big plane crash in Madrid-Barajas. Late in august 2008, a plane crashed in Madrid-Barajas leaving a death toll of 154. The network decided not to air that episode and start the season with the second episode.
The series release on DVD is a bit confusing: Three sets labeled "Season 2" parts I, II and III were released in 2004. These include season 3, not 2. Three sets labeled "Season 1" parts I, II and III were released in 2006. These include seasons 1 and 2, with "part II" set including the last 4 episodes of Season 1 and the first 5 episodes of Season 2. "Complete Season 11" set was released in late 2007. This is indeed Season 11, even if the cover shows a photo of Season 12 cast. "Complete Season 12" set was released in early 2008. This is indeed Season 12, even if the cover shows a photo of then recently finished Season 14 cast.
