On March 13, however, immediately
before leaving for the Pacific, he teletyped indicating that
his recalculations indicated danger of eye damage to ranges as
follows:
a, On the higher shot, to 560 miles for a person at
ground surface;
and 900 miles for aircraft at 20,000 ft.
b. On the lower shot, to a distance of 400 miles for
a person on the surface.
The basis for Dr. Ogle's calculations are contained in a
report dated March 1H, 1958, and now in the hands of DMA.

Graves, Bradbury, Dunning and Shelton,
all of whom believe the order of magnitude is correct though
the ranges are now estimated by all as somewhat

factor of perhaps 25%) than in Ogle's initial calculations,

a4, General Luedecke believes that he can establish,
through use of Trust Territory officials and Task Force
members, an organization which would have a fair chance
of preventing eye damage to the natives.
He could
establish control over air flights to the same end.
He
could sweep the area to insure that no shipping was
within the danger range at the time of the shot.
He
cannot, however, avsclutely guarantee that these or
ther measures will prevent inadvertent eye damage to
some individual or individuals,
b. Both TEAK and ORANGE could be fired in the daylight
with the yields now planned.
This would reduce the
estimated range of hazard to 320 miles for personnel at
the surface for TEAK and 180 miles for personnel at the
