NASA successfully launched first two in series of Nike-Apache sounding rockets carrying chemical cloud experiments from NASA Wallops Station. Rocket launched at 5:22 pm EST carried sodium experiment which created reddish-orange cloud visible for hundreds of miles. Rocket launched at 7:30 pm EST carried trimethylaluminum (TMA) experiment which created bluish-white cloud. Primary objective was to measure wind directions and speeds in 25- to 135-mi (40.2- to 217,2-km) region and temporal variations that occurred throughout night. Four TMA experiments and two acoustic grenade experiments, postponed because of cloud cover, would be rescheduled. (WS Releases 69-19, 69-20)
