Arizona gets visited by mysterious, UFO-esque lights

Phoenix residents think they may have been visited by UFOs Monday night. The four mystery lights hovered over the city for 15 minutes before disappearing. And, there's video:

It's a lot harder to be an alien visitor these days. Back in the 1950s, a UFO could appear over any mid-sized city, do some flips, blow up some cattle and leave. If anyone saw them, the aliens could rest assured that any witness would be dismissed as a maniac, a communist, or Ed Wood.

Now, every podunk in America has a video camera in their pocket, making visits difficult and necessitating clever disguises, like some groucho glasses or a funny hat.

I call this the 'Mike Skinner Phenomenon', which the Streets frontman brilliantly elucidates in the song 'When You Wasn't Famous':

Right see the thing that's got it all f*cked up now is camera-phones. How the hell am I supposed to be able to do a line in front of complete strangers When I know they've all got cameras?

Of course, for that to work, you need to replace "do a line" with "visit Earth" and "Complete Strangers" with "Hapless Earthlings".

Of course, they could just be sky lanterns. But that's not nearly as cool.

UPDATE: It looks like yes, they were balloons. Or maybe that's what the aliens want you to believe.
