morning, michael, why is terrorism being ruled out so early? >> it shouldn't be ruled out, there is nothing to reveal if it's a terrorist or accident. let's go to your earlier segment and something tom alluded to. statistics may show it to be safe an airplane takes off or lands every two seconds, throw out the statistics. the high profile crashes that we have have people on edge and what has to happen is to make sure, a, there is no relationship between these crashes, certainly the ukrainian one is an anomaly out of that and, b, that there is nothing systemic across the a-320 or the boeing airplane. that's why it's trickal to get those black boxes. so terrorism or suicide where one of the crew intentionally brought the plane down. but, you know those probably aren't what happened. i tell you, it will be a unique set of things we may get 30%
