Ascension Island missile-cassette recovery light (25 June 1960)
Late on 25 June 1960, off Ascension Island, a range vessel was recovering the data cassette from missile test 1802. As the small boat closed on the strobe-lit cassette, the boat crew, divers, an RCA photographer, a test observer and the crew of the recovery plane saw a steady light appear from under the surface about 100 yards away for some 10 seconds. Blue Book called it a flare, though no plane or vessel had released one.
How plausible · High
Range personnel in a boat, in the water and in the air saw the same light rise from under the sea during a missile recovery; the flare label fails because no flare was released.

Plausibility weighs how well an account fits where secrecy hides the documents by design, so missing records never count against it. Strength measures what is documented. Assessed 2026-10-24.
