 In Amsterdam, Schiphol Airport, which is one of the largest airports in the world, was frozen for hours on Friday morning. And this, Rick, was just an accident. It was just a glitch. It was not even a cyber attack. Just imagine, given how totally dependent we are on these invisible electronic systems, what would have happened, the chaos that would have ensued, if this had actually been done by some global nefarious actor. The world would have been in total chaos.
