opinion to the section head, he was encourage to undertake
the production of the necessary equipment.
Request for authorization and approval resulted.
In the past the project engineer has taken several aerial photographs
with a kite elevated camera using a simple box camera and operating the
shutter with a rubber band and a piece of fuse or punk, as described
in his book "Kites", published by the Boy Scouts of America, 1931. This
method would be too crude and unreliable for military purposes, and
in the first stage of development now (15 Nov. 1945) being undertaken
a light weight camera box of fixed focus, constructed in Special Devices
Division shop, is to be attached to a supporting frame in such manner that
the camera can be directed front, back, or to either side and inclined
downward at any angle. The shutter-opening mechanism is to be activated by
either a wind impeller gear-train or a pneumatic timer, whichever proves
most suitable. The camera box uses a standard 4" x 5"
plate holder. It is expected that with this equipment a number of pictures
will be taken to present to the Director and show the feasibility
of further development.
In its advanced stage it is hoped to perfect a camera which will incorporate
a spring-advanced film winder and an electric shutter, both of which can
be operated from the ground through wires in the kite line.
Although the project engineer is at this date being transferred from
the Special Devices Division to undertake assignment in another office, he
has requested that he be permitted to retain the Kite Elevated Aerial

Camera project and to work on it as opportunities permit, submitting
reports from time to time to the Director.

Supplement _____ illustrates a rectangular box kite which has
recently been completed and flown. It has excellent lift and stability
characteristics and should function well as a support for the Aerial
Camera.
