were faced with tne necessity of picking a wind pattern for
a high-yield shot which would put no fall-out on distant atolls,
and at the same time would not put fall-out on islands in
the shot atoll, for instance Eniwetok, we would be tremendously
handicapped ~~ therefore, in initial planning, all high-yield
shots are to be fired at Bikini Atoll, where close-in fall-out
will not seriously handicap the operation (assuming the Navy
will furnish ships for us to live aboard) and will be of little
hazard to personnel,
In firing a Bikini shot, we need then
only worry about long-range fall-out,
On the other hand, it is difficult and expensive 29 work
200 miles from our base of operations -- thus, low~yield shots,
which can be fired with relative safety with respect to close~in
personnel and essentially no hazard to other atolls, are fired
on the northern islands at Eniwetok Atoll,
Let me now tell you some of the reasons for the scheduling and placement of shots
in this particular operation,
I
have here a table listing the proposed shots for Operation
REDWING*.
There were left at the end of CASTLE, several in-
stallations in such condition that their use could be considered
again,
The recording stations in the Eninman region of Bikini
Atoll were not seriously damaged and a fair amount of land area
was left,
The Yurochi region, used for barge shots at CASTLE,
are still useable,
While a large hole was made in the reef
Just west of Namu, the island, itself, still furnished a fairly
large land area,
On Bogon of Eniwetok Atoll, the recording
structure used for Mike shot at Operation IVY was still in good
shape.
The recording structures on Aomon - Biijiri were built
for CASTLE and were still satisfactory,
*Note: Dr, Ogle will use only those portions of table covering:
fa) Particular shots which at the time of briefing have been unclassified;
i.e., Cherokee;
(bo) Particular shots foreign observers will see.
