Flight #3 (H/24 to 1/36 Hours): This flight will
attempt to determine the extent of drift of other
mjor soguonts of tho atomic cloud as practicablo
‘and as required by existing motoorological influonces, Areas and altitude of sc-rch are to
be specifiod lator and will be contingent upon
the above influvonces and tho results of flight
#1 ond #2, Specific instructions'forithis mission
‘will be forvdarded by CUTF. SEVEN to’ CIG 7.4, LATIN:
Commander, Test Services Unit, not lator thon

off,
Flight #4 (H436 to HY48 Hours):
Tho necessity
for schcduling this flight will bo determined
by CJIF SEVEN on the besis of the result of
Flights #1, #2, #3,and other sources,
Ze ifission instructions from CJTF SEVEN will be rout~
ed through normal command and cormunications
channels, However, to insuro that advance details
got to TG 7.4 sufficiently in advance of the mis-
sions, infornal mission instructions will be tran~
amitted through USS ESTES Woathor Central ENIWETOK Weather Stetion RATT channels by mission
take-off timo minus oight (&) hours for each
flight.
Tho basic requirement for cloud tracicing flights
is to provide data of sufficient accuracy to
support conclusions and decisions relating to
health hazards, and to confirm or modify forecast cloud segment drift. In genoral, the missions
are to be flown on tho tracks specified with max~
imum emphesis on complote coverage of the design‘ated arcas.. It is not anticipated that in flight
analysis of the overall situation will be necessary,
except that trackingaircraft crows should recognize cloud boundaries and leading edgos.
Deviations from tho prescribed track and reporting
positions should be mde only in the event of
entry into highly contaminated arcas. For cloud
tracking mission, turn-out will bo exccuted when
intonsitics of 3,0 r/hr ore approached.
Following
such turn-out, appropriate in-flight adjustmont
of track should be made by the aircraft commander
in the interest of mescimum coverage of the desig-
nated erca.
The rad/safe monitor will excrcise
discretion on turn-out from contaminated areas,
eerefully considering crew personnol dosages and
the anticipated longth of flight through thc
radiation field. Since precise measurements are
not required, suitable RADIAC equipment and reporting codes have accordingly boon specified
bolow,
ze
Each flight will havo on board sufficiont instruments of tho following types to insure reasonable
ctation of proper functioning of at least one
