3 flying saucers of Philadelphia on April 2017

On April 7, 2017, a passenger of an airplane has spotted three dark flying saucers over Philadelphia, PA.

Eyewitness states:

We were on a Frontier Airplane coming from Philadelphia, PA and preparing to land in Charlotte, NC close to noon on 4/7/2017. Our 7 year old son was sitting by the window. He told us to look out the window because he sees a spaceship in the sky. We took 3 pictures of the object in the sky. One of the pics shows 2 objects. If you zoom in on the pics, it does look like it could be something. Our son seemed so sure that it was a spaceship.
