Kevin Thomas and the Nimitz black triangle — A Nimitz petty officer says he saw a huge black triangle rise out of the ocean.
Kevin Thomas, a former Navy combat photographer, said in a TV interview that in 1991, while serving aboard the aircraft carrier USS Nimitz, he saw a huge black triangle partly out of the water a few hundred yards from the ship. He said it rose and then shot off at enormous speed, and that two men questioned him the next day and told him not to talk about it.
There's no official record of the sighting, and no other named crew members have publicly confirmed it. The Nimitz is famous in UAP history for a later event: the November 2004 "Tic Tac" encounter off California, when pilots including Cmdr. David Fravor chased an unknown object, which became public in 2017.
Thomas's account is one of several reports of large objects emerging from or entering the ocean near Navy ships. Congress has since asked AARO to examine such "transmedium" reports, and AARO has said it's studying underwater cases.
