Pack Forest, July 11,1968. Photography BROADCAST FIRE Closeup and distant photographs were taken for study of the action of the flames and the intensity of the fire and for study of the buildup and smoke migration. For the closeup pictures, a 16- millimeter movie camera was located at each of the four corners of the fire. The cameras were adjusted to take a frame every 10 seconds, viewing the fire at right angles from two sides, the north and the south. The distant cameras were located kilo- meters to the north and kilometers to the south. These were 16-millimeter movie cameras adjusted to expose one frame every 10 seconds. In addition, another 16-millimeter movie camera was used to take continuous pictures of the fire development from the instrumented aircraft. Also, 35-millimeter slides were taken sequentially of ignition and fire buildup, smoke characteristics, and all test operations. PILE FIRE Two 16-millimeter movie cameras, mounted to obtain pictures at right angles to each other, photographed the pile fires. The cameras were operated continuously for short periods upon two-way radio command. Still cameras took 35-millimeter slides of fire and smoke behavior and test operations. Meteorological Observations Instrumented towers, located on the southeast and the north-central portions of the broadcast area, monitored meteorological conditions during the broadcast fire. The north-central tower carried an anemometer and wind vane, mounted at meters to indicate the upwind conditions, but it was not functional during the fire. The southeast tower was meters tall. Psychrometers and anemometers, mounted at , , , , , and meters above the ground, moni- tored downwind conditions. A wind vane was 11. Please note that these images are
