the course of training is charged directly to the equipment program and

Logistics planning meetings have been held and it is evident that additional
coordination must be established. Spare parts, ground handling equipment
and service teams have been planned toward a 200 mission program opera-
ting at a rate of approximately eight missions per month. Logistics
plannings as revealed during meetings held at indicate that the STAT
highly mobile concept on which support equipment had been planned has
been modified to a semi permanent base concept operating at a rate of
48 missions per month from the first base alone.

5. 5 Test Site Operations
A total of eight photographic Test Flight Missions were accomplished
during November. Additional photo missions were scheduled, however,
they were not completed due to aircraft engine difficulties and inclement
weather.
Configuration A-1 was first flight tested in A/C 343. Results of the
Tri-Camera (HC-730) installation performance were satisfactory with the
exception of the data recording feature. Improvements are now being made
through engineering changes to correct this situation. The rocking mount
was flown on.one mission. Results from this evidenced improper operation
during the. first portion of the photo. run, after which the fault was cleared
and good to excellent results were obtained. The. detent and drive mechan-
isms were responsible for this maloperation and engineering design changes
have since been

Techniques in the handling and processing of the thin base film have.improved

were expanded and improved during the base' shut-down period from 20
November to 4 December. A new darkroom, 71 x 221 was constructed adjoining

approximately 15 December 1955. Space provisions in the new darkroom
will also accommodate the 70mm processing equipment expected to be
available in the near future..
Inadequacies of the shop and darkroom cooling system have been corrected
as provisions have been made for the installation of a temperature and humidity controlled air conditioning unit.
The first two men of the Field Service Support Team were assigned to the
Site on'8 November 1955 for indoctrination, training and to assist with
the Photo Test Flight Program. Photo personnel are maintaining ,a
