    "The operating system that drives the airline's flight plans went down."

    How in the world can they state that as singular. Surely they have a backup of some sort. Especially with all the supposed "increased security" around air flight, you are telling me that one system crash can knock out half of the major airlines? That's ridiculous. Have they not learned about redundancy?
