NASA successfully deployed and recovered 40-ft-dia parachute in final Project SHAPE (Supersonic High Altitude Parachute Experiment) test to evaluate possible use of parachute for aerodynamic deceleration for soft landings on planets with thin atmospheres. Parachute was ejected from five-foot-long canister carried to 33-mi altitude and 1,800 mph (mach 2.7) by three-stage rocket. Previous tests had been conducted Oct. 23 and Dec. 11, 1968.

USAF announced that data from preliminary investigation of effect of SST wing shape in creating sonic boom indicated that varying shape to reduce pressure field beneath wing might decrease wing's flight efficiency. Tests had been completed at Arnold Engineering Development Center in Tullahoma, Tenn, Tests also had been made to determine lift-to-drag characteristics of wing shapes upon which aircraft range and efficiency were dependent.
