Found: The Owner of a Message-in-a-Bottle Sent in 1983
(via Atlas Obscura) In 1983, the USS Coral Sea CV-43 Catapult One was cruising the Atlantic Ocean. The ship had an excess of small plastic bottles, meant to test oil… so they let the crew use them to send out messages into the open ocean. Ron Herbst wrote two messages, put them in two bottles, and dropped them into the ocean. Sometime that year, Gordon and Cindy Brevik found his message. It took 34 years for them to track down the sender.
