Was home, and wife of neighbor called excitedly saying that there were numerous orange objects in the western sky. She and her husband were coming home from the swimming pool and saw these objects in the western sky. My wife and I went outside and witnessed one object proceeding from due west at approx. 15% above the horizon traveling NE and disappearing behind a cloud bank northwest of our position at about 30% above the horizon. Saw two more similar spheres of same intensity traveling the same path over the next 4-5 minutes. Neighbors had previously seen several groups of these same objects traveling identical paths probably 30 objects in all with the largest single group of 7-8 orange spheres. Objects were very distant, so details of structures were not possible even though viewed through 12x binoculars. Objects were all traveling at same speed and path was straight with no variations. Neighbor, who is a retired Air Force test pilot said he could not identify what these were but they were definitely not commercial or military aircraft. Commercial aircraft proceeding to Tampa and Orlando airports were seen flying overhead during the witnessing of these spheres, so a comparison was possible. These spheres were not aircraft. Neighbor attempted to take video on his cell phone with limited success.
