Legacy was the only aircraft to have both a transponder failure and communication failure at a critical point in their flight. I am quite sure that most of the other aircraft flying that day could have fallen into the same trap.
I agree that both the loss of communications and the transponder failure are both layers of swiss cheese that were nibbled at or perhaps even devoured whole. I would like to understand just how important so I'm looking for some relavancy here.
I'm sure that there are some individual statistics on communication failures as well as transponder failures. Are these airways so crowded that if these two failure conditions combine together the flight is doomed?
Or do we have yet another ingedient or two that makes this accident stand out?
Else we had to have just a random roll of the dice where several ingedients had to combine together?
