The circular cloud we saw seemed to be approached by 6 or more small airplanes that seemed to be observeing the cloud. They would fly at it and veer away before hitting it. Also the circular cloud was moving against the wind.
One day gardening in the back yard with my wife, I saw a craft fly right over the top of our narrow little back yard & produce a contrail for about 500 feet. The craft was a shiney chromic sphere. Then, from where I was standing, it seemed to decend into the Naval Oaks Park that separates Gulf Breeze Proper with the Tiger Point area.
I have photos of what I beleive are ufos using "created" clouds. These are real photos from negatives or slides. I have been taking photographs of unusual aerial activity from 1990 to the present and many of these are clearly not clouds but actual lights.
Flying North along calif. coast at 5 pm @ 30,000 ft,& above
coastline clouds, I saw a small disk shaped (lintel?) cloud
traveling south, turn west between 2 cloud pillars, changed course
direction to north and at aproximately at a 30 degree
angle of decent disappeared into the cloud banks below.
