And Dick, you've never understood the problem that we aren't actually copying an integrated system. We're copying chunks of it. i.e. it's an unknown.
Well hello, they're flying as part of a mature system where everyone else is part of it, as opposed to a frankensystem where that everyone is new to. The chances of something serious going wrong for those two particular individuals - small. The chances of something serious going wrong amongst all the pilots new to the frankensystem - much much higher.
If our systems is soooooo dangerous why are you and the vast majority of pilots still alive having flown through it for decades?
