Little did this couple know what was lurking overhead when they pulled over near Millinocket for a quick photo.

It was late on a rainy Tuesday afternoon, Sept. 18, when these two people on a road trip through central and northern Maine stopped the car and took a selfie. Maybe the reason for their stop was that they may have admired the pristine Maine lake in the background and wanted a memory of the journey, but what they didn't count on or even see, was the object high overhead and lurking in the photo's background.

What was it?

The photo made its way to a family member the next day and that's when the mystique set in. The photo was uploaded to UFOStalker.com along with the following caption:
