You think the DoD would stand by and do nothing while a completed unidentified military surveillance plane circled a major city for days? Whatever this thing is doing, it's cleared at a high level. Maybe the people answering the phones for journalists don't know.

Not to mention that the last few days the Navy's been conducting an air show.

It was supposed to be a joke; of course I don't expect that. By definition, if it is undisclosed, then there is no source.
