And you know what? I believe him. I've worked in a government-like world forever, and it follows some simple rules:
-executives spend 99% of their time looking upwards.
-if some issue gets to them, it is assumed that their underlings failed, and they shoot the messenger.
-you can never admit you are wrong.
Naturally, every single person in hierarchy plays this game, so that nothing gets up, until it is a big crisis. Then all the action is, to spend money like crazy, and blame everyone. After the hubbub settles down, everyone gets a promotion.
I'm sure Lunn behaved in the same exemplary manner! Even if somebody jumped up and down on his desk, screaming "THE REACTOR IS GOING DOWN!" , he would look up with doe-eyes and say "What exactly do you mean?". If someone actually got through the hair, he would be shot.
