06-30-1970   MISIDENTIFICATION

Note: There seems to be some confusion regarding the sighting date. Early reports seem to put the date at June 10th or 11th. While later publications put it at June 29 or 30th (depending on the time zone it was reported from). I have used the 30th as it was the date of the crew’s sighting.-CF-   

HEYERDAHL SIGHTING SOLVED

Note: In an e-mail from researcher Jan Aldrich, I learned the following:        

”McDonald had a letter in his file from Heyerdahl, which said this was not a UFO. I can't put my hands on it right now, but Heyerdahl told McDonald the report was distorted by the press.”

Plumage of Navy "Bird" Gives Eerie Effect

       The sighting by explorer Thor Heyerdahl and two of his boat crew in late June (UFO Investigator, July 1970) has been traced to an unannounced rocket launch from Cape Kennedy. The launch was made on the evening of June 29 (June 30 for Heyerdahl, who was in a different time zone) to test the Navy's Poseidon missile. As the missile climbed into sunlight on its sub orbital trajectory, its exhaust spewed outward in ever widening circles, creating an amazingly geometric "cloud" that dominated the sky.

       The launch occurred at 9:31 p.m. EDT. This was 1:31 a.m. GMT, almost exactly the time Heyerdahl's navigator, N. L. Baker, first spotted a strange light on the northwestern horizon. At the time of the sighting, Heyerdahl's boat was some 700 miles out in the Atlantic, due east of the West Indies. This put him at the edge of the Eastern Test Range, which extends from Cape Kennedy into the North Atlantic. The Poseidon was launched down this range

       The distention in the phenomenon's shape as reported by the witnesses was due to the tendency of the missile to rotate as its second stage burned out. The contrail from the spiraling rocket created a "pinwheel" effect, which was enhanced by the rays of the sun. Heyerdahl could only see half of the pinwheel because the Earth's curvature obstructed his view.

       This is not the first time a Poseidon launch has generated UFO reports. A similar shot in August 1969 set off sightings throughout parts of the Caribbean and the United States. A year before that, on August 16, 1968, a sighting in South Carolina was tied to the first developmental-launch of the Poseidon (see the picture below).
