CPS-l radar reportedly '~~oke into three smaller contacts maintaining
an interval of about ~4 mile." Thp blips on the CPS-l were described as
small and relatively weak, but sharply defined.
Two things seem apparent: (l) the object seen at Haneda and
Tachika~'a AFB was much farther away than the observers "l:'ealized;
(2) the visual UFO and the target tracked by radar were not the same.
The first statement is supported by the inability of tre ob56rvers
at Shirai to see anything to the south; the second statem~nt is S'Jp-
ported by numerous inconsistencies between the visual and radar
sightings. Tht: two most important of these latter are: (1) During
times when the Gel rauar could not find the target, the visual object
was in about the same location as during those times when it could be
found on radar; (2) lhe visual object was seen for at least five min.
after the time when the airborne radar on the ~-94 indicated that the
UFO had left the areCl at a speed well in excess of 300 mph.
