       On April 19, 1957, at 11:52 A.M., two metal disks were seen entering the Pacific Ocean at 31°15' N. and 143°30’ E. A violent turbulence followed their immersion. The witnesses were Japanese fishermen on board the Kitsukawara1 Maru. The point in question is among the deepest in the Pacific Ocean (more than ten thousand meters deep).

       The Japanese fishing boat Kitsukawara Maru was sailing south of Yokahama [sic] with its five man crew on April 19, 1957. All hands saw the sudden appearance of two silver saucer-shaped metal craft plunge into the water nearby. Immediately afterward, the sea where they fell became furiously disturbed, boiling and churning violently. The crewmen searched for wreckage but foundnothing.

       On the 19th of April, 1957, crew members aboard the Kitsukawa2 Maru, a Japanese fishing boat, spotted two metallic, silvery objects descending from the sky into the sea. The objects, estimated to be ten meters long, were without wings of any kind. As they hit the water, they created a violent turbulence. The exact location was reported as 31° 15' N. and 143° 30' E.46

ALSO (For additional information)  

At 11:52 a.m. on the 19th, the Japanese fishing boat Kitsukawa Maru was en route to Japan from the South Pacific Ocean. The bosun and four crew members spotted two metallic, very silvery craft descending from the sky and suddenly dive into the water at about 143-30 E., and 31-15 N. After the craft submerged, a violent turbulence occurred under the surface where the objects vanished. The bosun thought at first the UFOs were jet planes, but they had no wings and were approximately 10 meters long. His boat searched the area but found no wreckage. (S.P.A.C.E.magazine, July 1957)

Notes 1 and 2: The spelling of the ship’s name varies with the authors’ reference used, Kitsukawaraand Kitsukawa. I do not have the correct spelling at my disposal at this time.-CF-
