"With the air traffic patterns in the Valley, what we see are a lot of stacked aircraft that are coming into Sky Harbor," said Dr. Sky, a TV personality and radio host of a talk show that's syndicated across the country and in Canada.

"I'm 41 years old. I've seen a lot of things in the sky," said Christinna Herrmann. "This is nothing I've seen before."

So, was it a UFO?

"Anything that you, or people, saw that we call a UFO is simply accurate," said Dr. Sky, solely because we were not able to identify it.

So, was it aliens?

"Firmly I believe that we already know about alien visitation," Dr. Sky said, citing the Roswell incident from the 1940s. "We're going to continue to search for what [everyone] saw in the skies of Arizona."
