How much more would you pay for admission for the convenience of duplicating the fire/paramedic/other services?
That policy is just lawyer-speak, dictated by some bitchy "risk manager" who was hired to make sure that no "risk" is ever assumed. I, for one, refuse to live in their world.
Further, I defy anyone to come up with the odds of having two serious crashes on Wittman Field simultaneously, where the second accident occurs before the first one is properly dealt with. I suspect that your odds of winning the lottery are significantly greater than of this happening, but we'll have to ask an actuary to chime in here.
If the odds are, say, a million to one against it happening, should we still close the airport when there's a single incident? 10 million to one? When is the risk low enough to satisfy a person who is paid to assess risk?
However, even if you allow these people to dictate your reality, there is little or no extra cost IF you can obtain volunteer airport fire fighters from, oh, say, Mitchell Field in Milwaukee, or the Air National Guard in Madison. I suspect that would take a few phone calls, and a few free passes.
The consequence of closing the airport is sending people somewhere else. Big deal. If you want convenience, pony up.
No, the consequences are the greater risk of a mid-air collision somewhere over the tracks between Ripon and OSH or around the lakes due to sudden saturation. I'm no mathematician, but I suspect the odds of that happening are significantly higher (due to airport closure) than the odds are that something bad will happen elsewhere on the airport because they left the other runway(s) in operation after an accident at the other end of the airport.
And, of course, there is no cost for the FAA to implement common sense. (Although rumor has it that there will be a new tax on it in the 2011 Federal budget...)
