At tuestart
of th
theoperational period, ni ht flizhts and overawitur
flichts were generally arranced with no creat diificulty,

After the une

Avril, there were so many restrictions placed on ii-ht and overe-water fly-
ing that. i€practically stoned.
Personal examination by CTG 7.4 of re=
quests for such flichts res:lted in nany celays in getting TG 7.1 require-
ments accepted.
In manyevents, ‘articularly ‘Jahoo and Umbrella, the var-
ious scientific projects were hamstrung by the limitations on helicooter
operations,
This was relieved somewhat by use ofmarine helicopters which
had fewer overational limitations.

The major problem was that arrangements made tetreen the TG 7.1 and
TG 7. staffs were frequently cancelled by J7G 7.4 shortly Lefore the vlan~
ned t‘'me of execution.
To experimenters onerating on a closely timed
schedule of events, such cancell-tions were almost ruinous,
After many dis-
cussions between J=3 of TG 7.1, CTG 7.4, and finally J-3, JTF SEVEN, TG 7.t/
developed a noticatly less reluctant avproach toward supporting TG 7,1 re=
quirements,
This became evident during may; and, by the zee of June, the
situation had improvec to the point where staff level arrangements could
arain satisfy nost onerational requirements.
