"No place was a worse reminder of what Pittsburgh had lost than its airport.
Pittsburgh built that airport with one client in mind: US Airways. 'We built it for USAir,' Allegheny County executive Rich Fitzgerald said later, 'hoping that they would grow jobs here.' The airport’s biggest funding source was $600 million in county bonds, which the county would, of course, have to pay back. The plan was that USAir fees would cover the bulk of those payments over the next few decades. Everyone felt pretty good about this arrangement at the time.
Then, US Airways fucked over Pittsburgh very, very badly."
