I had to watch this twice because I realized that sometimes when I watch documentaries, the authoritative narration is so soothing that I miss the point and walk away having no idea what I just watched. Nova: Crash of Flight 447 is a good episode, but it was unfortunate that the experts didn’t have all available evidence to examine & a key piece of the plane’s equipment is missing so there are no definitive answers to determine whether they are right or not. Still try to avoid flying in a plane across the Atlantic at night was my takeaway.
