Interesting how these threads about aviation catastrophes precede along relatively intelligently for about three pages, typically brief discussions between professionals, and then at about page four, the hysteria begins. The SLFs begin to chime in with their inept theorizing, the Microsofties ruminate about how they'd have handled the situation with their keyboards, the conspiracy theorists appear out of the aluminum... These threads have a definable half-life, and it begins to come apart at this point.
