Mr. Skinner, do you have any idea—and of course Mr. Hann and Mr. Breen are also involved in government and budgeting—of what the cost might be? We've heard different numbers thrown out. I don't know how accurate any of them are, although I've seen a study, which I referred to yesterday, showing that the cost of having a 30-minute, 24-7 fixed-wing operation would cost $1 billion over 30 years, which was a billion dollars extra and which of course breaks down to $33 million a year. That's just for fixed-wing across the country.
There were other numbers thrown around. I hear numbers like $200 million. I hear other numbers. We don't know what the numbers are. How big a factor is cost, from your point of view, given the nature of what we've been discussing here today, given the numbers involved, the risk involved, and the people involved? How big a factor should cost be in determining whether we go 24-7 on the 15- to 20-minute standard that you're talking about or whether we have a different system?
