safe time interval after the weapon or device had been armed to allow complete evacuation of the atoll when necessary, and to permit the Firing Team
to retire to the Control Room, When a shot was canceled within 2 hr of
zero time, the Disarming Team cntered the xcro area after the timer opened
the arm line. On some of the smaller shots at Eniwetok where the diagnostic measuremen.s were not restricted to a certain early time period, the
snfe separation timer was set to open the arm line up to 8 hr after zero
time. This provided severa! hours in which zero time could be rescheduled
when the weather was uncertain. When possible the arming operations were
conducted during the daylight hours, but on several occasions it was necessary to arm after dark, Transportation for the Arming Team was provided
by plane, helicopter, or watercraft, according to the type best suited for the
particular zero location.
Firing was accomplished from a Control Room by starting, 15 min
befure zero, a motor-driven timer which automatically provided the timing
sicnals, There was a Control Room at Parry, Eniwetok, ané Enyu, Btkint,
The Control Room at Enyu could be remotely contvolled by radio from the
USS Curtiss. Bassoon was the only test where the’remcte station aboard
the USS Curtiss was used,
Several disarming operations were concucted at both atolis because of
postnonements due to unfavorable weytier conditions,
Only one disarming
was concucted under an emergency situation, This was on
“after the
shot had been eanceled with 3 min of zero time because off” ”
