this before. a lot of criticism heaped on their heads. how much is deserved in your opinion? >> i feel like we're watching them learn how to conduct an air crash investigation. that's an unfortunate thing. a steady hand and some experience would be good in this case. ways talking to former ntsb chairman jim hall said. he said if a nation is buying something as complex as a 777 it should be able to demonstrate it has the expertise and capability to perform and conduct a thorough investigation if something bad happens. and if they can't demonstrate that, perhaps there should be some sort of memorandum of understanding with another nation that has that capability. in this case maybe australia or new zealand or the united kingdom. whatever the case may be. so i think there's a responsibility when you're flying something as complex as a boeing 777 to be able to conduct an investigation like this. because it is really, as we're talking about it here right now, it is a global issue. the whole world wants to know. and there are a lot of boeing 777s in the air right now.
