Abstract : The purpose of the Flat Top program was to photograph the fireball, shockwave, base surge, ejecta, and early and late cloud formations on each of three separate high-explosive detonations used to simulate equivalent detonations of nuclear devices. Excellent results were obtained on 16-mm, 35-mm, and 70-mm black-and-white film and 35-mm color film. Detailed descriptions of the photographic instrumentation and representative samples of the film records from each of the three events are included in this report. Recommendations for improved coverage on future experiments of this type include the use of an additional close-in photo station, faster framing rates, the use of a timer as a backup on camera shutter closure systems, and more extensive use of color film.
