Giant Radar Return Reported to Air Force PBB
February 19, 1958
Hokkaido, Japan

Dan Wilson:
Feb. 19, 1958; Hokkaido, Japan (BB)
9:59 p.m. local. While conducting surveillance of Russian aircraft, operations personnel of AC&W Site #45 at Asoiwayama, Hokkaido,observed an unusual radar return. Radar report from the Sea of Japan area. Radar return developed rapidly to a dense cloud that expanded to cover an area approximately 65 miles long and 25 miles across and rose from an altitude of 3,000 feet to 46,000 feet. Five aircraft (Russian) in the area all turned toward the return and proceeded to the general area. A seismic detection of a nuclear explosion was reported from Matsushiro. (Dan Wilson)

At this same time frame at Okinawa, Japan, and surrounding areas a mock atomic battle was taking place. Operation Strongback -a massive atomic mock battle was taking place from Okinawa to the Philippines. UFOs would probably be interested in this event, as they were in Operation Mainbrace in 1952.
