However, you have to keep some perspective.
How would a one day stop compare to a large winter storm's effect on aviation? How would it compare to the days after 9/11, or the early August 1981 air traffic controller strike?
It's difficult to gauge the effect of a one day cessation of air traffic in comparison to, a week (or two?) of the services that are being shut down now, and say it is necessarily worse.
How would it compare to the economic fallout of putting off progress in health care yet another decade or two?
Furthermore, maintaining focus on keeping perspective, even a single day delay in payments on US securities could be the economic equivalent of the apocalypse, and yet that seems to be on the table for the craziest of the crazy legislators.
There's a lot of discussion about what would make the issue more concrete, and people talk tough about how Congress shouldn't be paid. If they really wanted to inspire them to find a quick solution, maybe all general aviation across the country could be shut down. The economic fallout would be much less, but people who get a direct line to congressmen would tell them to get to work.
