These three pictures were taken while on a ferryboat in Greece about 40 minutes into an hour's trip between the port of Rafina and Marmari. Kolpos Petalion38.050803, 24.171313 (exact location on Google maps, and camera was facing south)It was very windy, and the sea was so beautiful, that I decided to go out on deck and take a few pictures to use as background on my desktop at home. The pictures were taken with my HTC One X phone.I never noticed anything odd at the time, but when I got home and put picture # 104 up as background on my 27" screen I saw the black shape protruding from the clouds on the upper right corner. As all three were taken within a few seconds, I looked at the other 2, and it's obvious, whatever this was, was hidden in the clouds since you can still see a small bit of it in pic # 105. I honestly don't know what it is. There are no flights over that area, and it's obviously not a helicopter as it was very windy and it wouldn't be hiding in the clouds. Hopefully with your equipment you'll have some kind of explanation of what this could be.Thanks
