Other photo stations included a barge, an
observer ship, and surface stations on Igurin and Mui.
In
addition, cameras were located inside the hull of a ship to
record the effects on the ship's structure of the shock resulting from the detonation.
EG&G provided special lighting
apparatus for this experiment.
Planning for Newsreel on Johnston Island includes three
ship-board photo stations,
two aircraft photo installations,
and six mobile and stationary ground installations.
Operation of the photo stations was completely automatic.
Timing signals from the Control Points activated the control
equipment and the cameras.
Cam timers permitted cameras to
continue operating after the timing signals dropped out at
# 1 second.
Signals to surface photo stations were trans-
mitted by wire; aircraft,
shipboard, and remote surface
stations were operated by radio signals.
Film recovery was made as soon as possible after a
detonation.
EG&G maintained complete film processing
facilities on Parry Island at Eniwetok.
Results.
.
EG&G performed analysis of fireball records at the
Eniwetok Proving Grounds.
Analysis for other projects will
be accomplished, as required, in the United States.
Precision
equipment was employed to measure fireball diameter, and the
data obtained were reduced on an IBM 704 computer.
