UFO Sighting in Aberdeen, Maryland on May 27th 2015 – Noticed commercial aircraft doing u-turns. Noticed these 3 objects when reviewing the images. Saw nothing when I took photo.

We noticed several commercial aircraft making u-turns when eating dinner on our porch. I took some images of the contrails because that is something I don't see where I live. Later that evening as I looked over the images, I noticed the 3 circular objects. I did not see them at the time the image was taken.
