was no rescue work involved in the whole operation on "X" day.
The tank operation was successful up to a certain point.
Several
ground samples were picked up by the tank which was directed by an
operator in helicopter hovering above Fngebi Island.
These were re-
turned to personnel at the far end of Engebi, but they were too weak
to be of much valve.
The tank was then directed into the crater
where, because of unfavorable terrain features, it became inoperative
in spite of continued transmissions fran the electronic control on
the helicopter.
It. was decided that the stand-by tank should not be
directed into the crater because it too might become inoperative in
a dangerously radioactive area and, as a result, there would be no
radio-controlled tanks available for the second and third tests.
Those
samples which could be recovered by helicopter were returned safely .
to the BAIROKO.
Shortly after detonation occurred and as soon as sufficiently
daylight was available, the liaison aircraft carrying photographic and
radiological safety personnel took off from Eniwetok to collect exposed
film and establish radiological safety areas.
Photographic operations on "X" day were considered to be success-
ful from the standpoint of both the technical and documentary phases.
A number of the aircraft reported operational failure of certain types
of cameras, but it was estimated that at least 85% operated satisfactorily during the test, although actual results cannot be evaluated
accurately until all film is developed.
