I shall return on 11 November.
In case you're curious about the header image, that is the Liberian Tanker Ocean Eagle sinking in the harbor off of San Juan, Puerto Rico on 3 March 1968.
The accident was devastating to local ecosystems as it was the most severe oil spill experienced in U.S. territorial waters up to that time; in its wake came improved methods for containing spills and improved tanker safety practices.
I have gone through various U.S. government publications, however they are careful to remove references to owners and the name of the ship's captain. If anyone might know of the shipping company that manned the ship at the time of the accident, I would be keen to obtain their hat badge.
