The witness report:
Came outside for a smoke facing west on a clear sunny day with a few clouds at 11:27 am on 10/16/17. We have a lot of air traffic in the Tampa bay area. I noticed a dark rectangular object at 33 degrees to the NW over a mile away. I thought it was a bird gliding at first. Dark with no reflection from sun.
Sun was still in the east and object was west so it should have been bright if it were a plane. We are subject to military aircraft such as black hawk helo’s.
Object appeared a thin rectangular object and moved south in front of clouds for several seconds. In less than a mile and aprox. 100 mph it just vanished. No cloud cover when this happened. I tracked it’s known path for a while to see if it would reemerge. It did not.
Then I noticed my eyes were full of spots every time I blinked. Similar to a photo flash but in a 20 X 20 grid of dots. This is not unusual looking up in the sky in Florida but not when looking away from the sun and not in a grid pattern. Not sure what I saw due to it’s distance. I know I was fully awake and conscious and saw this event clearly. The object would have been over the Gulf of Mexico at least a mile out.
