MEMORANDUM FOR: See Distribution
SUBJECT: Mission 1105 Flight Plan
25X1A 441EFERENCE: Dated 9 August 1968
1. The purpose of this memorandum is to re-state the flight plan
of Mission 1105. The projected flight plan of this and other upcoming
missions was originally disseminated to the addressees through the
above referenced memorandum.
2. KH-4B, Mission 1105,
will be configured in the following manner:
a. There will be no Dual Improved Stellar Index Camera
(DISIC) on this mission. All vehicle/camera attitude information
will be derived from nominal values and horizon imagery.
b. SO-380, ultra thin base (UTB) film will constitute the
primary film load of both panoramic cameras. The use of UTB results
in a film load increase of approximately fifty percent. There will
be approximately 48,000 feet of primary camera film compared to the
normal 32,000 feet of 3404.

c. The use of UTB film necessitated a change in the film roller
configuration (for this mission only) which resulted in an increase
in the format length. However, there has been no film metering
modification. Therefore, there will be image overlapping between
every second panoramic camera frame and horizon image pair. The
overlap will be approximately 0.25 inch and will involve the bonus
area (out-of-focus) of the panoramic camera photography and the terrain
side of the horizon imagery. The NPIC component responsible for deter-
mining attitude from the horizon photography, has concluded that the
overlap will render the attitude solution weaker but will not constitute
a serious degradation.

d. There will be 500 feet of S0-121.Ektachrome, tri-pack
reversal color film exposed during the mission. It will constitute
the last 500. feet of the aft panoramic camera film load and will
be exposed in stereo with the forward camera black and white record.
The S0-380 and S0-121 film thickness difference will result in an
estimated 300-500. feet of S0-380 forward camera film available for
monoscopic coverage. To alleviate an abrupt film thickness change
in the camera system, a 50 foot section of film type 3404 (standard
thin base) film will be spliced between the S0-380 and the S0-121
(standard base) films.
e. A third generation Petzval lens will be used in the forward
camera and a second generation Petzval in the aft. The difference
in lens design should result in a significantly better product from
the forward camera than from the aft. This is the same combination of
lenses used on Mission 1104.
