UFO squadron photographed from our helicopter over Brooks Mountain Range Alaska, about 70 miles north of Bettles, Alaska on return flight from the Arctic. We were flying on a heading of due south and the unidentified craft were on a northerly heading. Was the only shot I was able to get, they moved behind us at a very high rate of speed. This was taken in October 2013. You can definitely make out the lenticular shaped craft when I enhanced the photograph, I am a pilot with 33 years experience and this was the first time I've seen a UFO and just happened to be a total of 8 unidentified craft. They do exist!
