UFO near the Mount Rainier, Washington

On April 2014, an automobilist, that drove near the Mount Rainier (in the State of Washington), has photographed an unidentified flying object. Object is blurred, but photo is real. What is it?

Witness statement:

I was driving east towards Mt. Rainier in a town called Buckley Washington. It was around 9 or 10am and I was attempting to get a good picture of Mt Rainier with my cell phone camera. I took several pictures while moving and it was later when I got home I noticed in two images there was a grey colored object. I did not see these objects when taking the pics only observed in later photo review. When you zoom in on both pics the objects are to left of the signs. Photos taken with samsung galaxy smart phone.
