Program Six DOD(NOL) Project 6.13 Measurement of Free Air Pressures by Rocket Photography ' (zeter Hanlon) One phase. To make indirect measurement of free air pressures near bomb zero, One shot (KING). This project will utilize high speed photography of a grid in space. The latter being supplied by smoke trails from previously fired rockets. Shock wave passage causes detectable perturbations in the grid; hence Te Reentry when radiological conditions permit.
