The Federal Aviation Administration recently approved the Philadelphia International Airport’s $5.2 billion expansion plan. The airport wants to lengthen two runways and a build a fifth one to address continual congestion and delay problems. But to expand the airport, 72 houses and 12 businesses in Tinicum Township would have to be demolished. This hour, we’ll talk about the expansion plan with the airport’s CEO MARK GALE, and hear from Tinicum resident DAVE MCCANN, President of the citizen’s group Residents Against Airport Expansion in Delco or RAAED about what the plan would mean for Tinicum Township. Then we’ll shift gears and talk about the media’s obsession with Sarah Palin. Washington Post political columnist DANA MILBANK has called for a “Palin-free February.” He’s vowed not to write or talk about her for one month.
