Regardless of the facts, the story's out of control and the airport's in trouble. The rules are simple, these days - even if you're right and there is no real problem, take it on the chin and do whatever it takes to fix the perceived problem. The airport has to shut down, do whatever work is necessary, and come back fresh.
Otherwise, the story keeps creeping up the news - more carriers restricting services, more punters choosing not to take flights in (there is no journey for which Brizzle is the only option), and the excuses coming from management sounding more and more specious every time. They already sound like amateur hour at Club Spin; they're going to sound like a P45 in blank verse by early next week.
This is regardless of the facts.
One of the first companies to learn the rules of the new news environment was Intel with its buggy Pentium. The company was dead right - it was a very minor bug that would affect almost nobody, and absolutely no reason to recall all the chips. The customers thought differently - and, after a brief and very embarrasing battle in public, they won hands down.
