3,

I do not have the figures as to the number of persons

and the costs involved in the high-altitude program.

Such

costs are almost impossible to segregate in that certain
construction and instrumentation is used for several experiments

and many personnel work also on more than one experiment.
However, I estimate that cost must run between $10 and $20
million and I would estimate the maximum numbers of people

directly involved in ecientific effort and support to be in .
the range of 1,000 to 1,500.

Measurements contemplated are

as follows:
|

a,

From peds shed from the Redstone missile rockets,

to measure thermal, gamma, and neutron phenomena at
various distances from the blast.
b.

By rockets emplaced in space around the higher

shot, to secure similar measurements.

ec, Prom aircraft, to measure through photograrhy and
other instruments the rate of growth, and spectrum, of
the fireball together with the intensity of the various

“phenomena at the airoraft altitude,

ad. Through one rocket for the higher altitude shot to
capture a debris sample for analysis to determine
feasibility of getting yield in this manner.
Also from

one rocket on the higher altitude shot, to attempt to

transport radio signals through, and around, the cloud.

e. From stations on the ground, to photograph the

fireball and determine its spectrum and to determine
thermal effects, etc., received on the ground near
detonation point.
f, From close-in and distant electromagnetic and
microbarograph stations, listening stations, and radio
and radar transmission receiving stations to determine:
detectability through these high altitude detonations,
and interference of such detonations with radio and
radar activity.

4, The Eniwetok Planning Board reviewed some months ago
the thermal effects to be expected from the detonations and
judged them to be reasonable.

In the briefing of the Commission

on February 28, 1958, Dr. Ogle indicated that the danger to eyes
was expected to be in the neighborhood of 100 miles, and
