Many of the UFO cases in the Vietnam War are not verifiable and are mostly passed around as stories between soldiers.
One such story is that of crewman Norman Burns’s odd encounter with a water UFO near the end of the war. At the time, he was serving on the USS Kilauea during a patrol of the Indian Ocean.
One night in 1974, Burns and a friend were standing on the deck of their ship, idly watching another ship in front of them in formation. The ship was kicking up a trail of phosphorus algae behind it.
Suddenly, the trail began to glow and got extremely bright. Out of nowhere, a ball of light leaped out of the water, rolled over the destroyer, and dove back into the water. Burns recalls that the ball was 150' to 200' in diameter. Everybody on watch also saw the light, but no one was able to identify what it was.
