We were in a ferryboat from Woodshold MA to Marthas Vineyard taking pictures of the shore on 5/23/15,at aprox. 10 am. We did not realize that some of the photos contain something not usual up to now.First picture contains a rare small cloud in a perfect clear dry morning of May. No other clouds in the whole sky that morningGetting the photo to my PC and zooming to maximum we discover something dark over the cloud with a distortion of the atmosphere all around the cloud.Second picture of the shore, 10 min later, contains a round object seen on the left side over the small cliff, suspended on the sky.As an institution you have more precise ways to confirm if the supposed objects are real, I would like to know if we really have a UFO in our pictures.Thank you, you are doing a tremendous effort to discover the truth.Pedro
