U.S.S.R. launched Cosmos 435 from Plesetsk into orbit with 478-km (297.0-mi) apogee, 272-km (169.0-mi) perigee, 92.0-min period, and 70.9° inclination. Spacecraft reentered Jan. 28, 1972. (csFc SSR, 8/31/71; 1/31/72; SBD, 9/14/71, 27)
NASA'S supercritical wing, flown on TF-8A aircraft piloted by NASA test pilot Thomas C. McMurtry, successfully completed 10th flight from FRG. Objectives of 40-min flight were to obtain additional pressure distribution and performance data at high subsonic speeds and evaluate flutter characteristics at low supersonic speeds. Aircraft reached 12 000-m (40 000-ft) altitude, with pressure distribution and performance data obtained from mach 0.80 to 0.97 and flutter characteristics evaluated at mach 1.05 and 1.10.

Experimental, quieter jet aircraft engine was undergoing noise tests at Peebles, Ohio, LeRC announced. Engine was being developed under contract by GE's Aircraft Engine Group. (LeRC Release 71-38)
Effects of levels of ionizing radiation on passengers and crew members in supersonic aircraft flying at 18 000 to 20 000 m (60 000 to 65 000 ft) were described in Science by USN biophysicist Hermann 7. Schaefer. Level of galactic radiation per mile for SST was smaller than that for conventional jet aircraft. "Even in the extreme case of some-one's spending, for a full year, 10 percent of his time at SST altitude, the integral dose equivalent would still not exceed 1 rem." Increase in risk of shortening residual Me-span was "insignificant." (Science, 8/27/71,780-3)
Easier relations between Soviet and visiting foreign scientists attending 15th International Union of Geodesy and Geophysics in Moscow, Aug. 1-14, were reported in Science by Philip H. Abelson. "To an extent not previously possible, Americans were entertained professionally and socially and were invited to visit Soviet research facilities. Only a few Russians would be so bold as to act counter to official policy in their contacts with foreigners; therefore, the extent of the hospitality reflected national policy."
