Swiss physicist Dr. Johannes Geiss, originator of Apollo 11 experiment to trap atomic particles from solar wind on lunar surface, would use "deliberate speed" in assaying results, New York Times reported. NASA courier had delivered square foot of aluminum foil exposed on moon for an hour to catch particles emitted by sun. Dr. Geiss and associates in Berne Univ.'s Physics Institute had devised plan for dual study of foil in Berne and at Federal Polytechnic at Zurich. Analyses, determining components by spectrometer, would require several weeks. NASA would not release remaining three square feet of foil to him until 1970. (NYT, 8/18/69, 34)
British Aircraft Corp. and Sud-Aviation announced completion of second phase of Anglo-French Concorde supersonic transport flight development program. Two prototypes were being readied for transonic phase to push aircraft's speed beyond mach 1 in early September. Two prototypes had logged 104 flying hrs in 39 and 24 flights and had achieved speeds to mach 0.95 and altitudes to 40,000 ft. Concorde 002 was being prepared for supersonic flights to mach 2, or 1,400-mph cruising speed, in tests expected to begin at year's end. (BAC/Sud-Aviation Release 10C/69)
