Purely as a layman I thought the program was a tad biased against Airbus - i.e. the accident happened because it was an Airbus - so it's interesting to see that Boeing released a memo advising against using the multiple rudder reversal procedure on their planes too (as stated in a post above).
I also had the feeling that there was something missing from the program and that maybe the producers knew something that they were not allowed to broadcast (maybe for legal reasons) - it was the kind of feeling when you watch a film that ends open-ended and you kinda of go "and then what happened"? Did anyone else get that feeling?
I also thought it was a nice sensitive gesture not to broadcast the actual voice recordings as the plane was about to go down - it's not nice to listen to and should be kept private for the families and investigators involves, imho.
May they rest in peace.
