Air Crash Investigation is watchable, even if they do generally squeeze 30 minutes’ worth of material into an hour. It’s easy to pick holes in the show as a professional pilot, but it does get at least convey the basics of an event and subsequent investigation.
It would benefit from more technical research and input from professionals in the industry, as opposed to all the ‘human interest’ padding about what the passenger in 7C had for breakfast that morning (although I’m sure it helps keep production costs down).
I thought Channel 4’s ‘Black Box’ series was a much better effort.
