Well, there is the fact that the roof fell in that can help make people nervous too, espc when they basically admitted the design was flawed and would require years of renovation and redesign to make safe. I realize no one flies into that terminal at the moment, but I'm just pointing that one out.
(It wouldn't stop me, but I know people who take that kind of thing seriously. People already have issues with flying, don't let airports collapse on people too, etc...)
