Did not see with the naked eye. i was shooting video of the moving storm clouds. i shot a 13 sec. video later watching the video. i saw the 4 objects heading in the direction of fort hood. in the center top of the video, you can see 3 moving very fast in a decent. a forth one to the right moves forward to complete a formation. i curve of 4 objects. the velocity is too fast for a jet or a bird. also how the one seems to fly directly into a formation with the other 3.
