"All in all, we're not even asking GA to pay their full
share. Though they impose 16 percent of our costs — I alluded
to this figure a minute ago — we're asking them to pay 11
percent, with the rest coming from the general fund... The aviation
community knows more so than others how high the stakes are. If
Congress doesn't act on our proposal by September when our taxes
expire, we're all going to feel the pinch. And it's a pinch that's
going to last for ten years."
