This report includes data and results which were obtained during plume rise experimentation. Aircraft plumes were photographed using the smoke-producing F-102 drones, and Thunderbird T-38 aircraft. The second set of experiments indicated that, under low wind and unstable conditions, the aircraft plume not only rises but completely separates from the ground. The other studies, however, indicate that under high wind and neutral conditions, the plume rise is greatly retarded and there is no significant ground separation. Differences in micrometeorology apparently account for these plume rise variations. Since the 13 tests performed are inadequate to understand the causes for the plume rise and ground separation, it is recommended that this study be extended in order to provide an explanation for this phenomenon.
