UFO/USO video footage:
Gulf of Mexico — Early May (probably) 2010.
My comment:
The UFO flies through the Corexit spray before going under the sea.
Quote from the Wikipedia article, “Corexit”:
“A U.S. Air Force Reserve plane sprays Corexit over the Deepwater Horizon oil spill in the Gulf of Mexico.”
The Deepwater Horizon drilling rig exploded on 20 April 2010.
