Penny-wise and pound-foolish - Congress and the FAA reauthorization bill

I am pleased Congress reached agreement on the debt limit. I understand it took priority over all other legislative matters for the past few weeks. I also understand there are philosophical reasons to debate the budget for the Federal Aviation Administration (FAA). I do not understand why Congress would take a recess before addressing the FAA reauthorization. A temporary extension until Congress reconvenes seemed a reasonable compromise. Instead, the government cannot collect federal airport taxes, the FAA furloughed 4000 employees, and many airport construction projects are on hold. Has anyone noticed the economy is weak and tax revenues are down? President Obama correctly characterized the situation as "another Washington-inflicted wound on America."
