On BBC iPlayer and still available for about the next month, the G-BWFC accident is revisited in Series 1 Episode 2 of "The Disasters That Shocked Scotland". The BBC progamme is focused less on on the technical aspects, but rather more on the personal accounts of the two survivors, one of whom was the Chinook's captain.
