XB-70 research aircraft, flown by Fitzhugh L. Fulton, Jr., and Donald L. Mallick, reached mach 2.55 and 67,000-ft altitude and accomplished 70% of primary test objectives during 1-hr 54-min flight from Edwards AFB. Purpose of flight was to take wing tuft photos and check stability, control, and handling qualities; inlet performance; boundary layer noise; friction; fuselage bending. (XB-70 Proj Off)
Most realistic way to reduce sonic boom from supersonic aircraft was to make successive small reductions, according to Generation and Propagation of Sonic Boom, report of Subcommittee on Research, NAS Committee on SST-Sonic Boom. Reductions could be achieved by "refinements in conventional aircraft design, a better understanding of theory, and improvements in propulsive efficiency and operating procedures." Future aircraft designs might yield significant' reductions. Studies should be undertaken by both Government and industry on "less conventional configurations."

NASA awarded $7,178,937 contract to General Dynamics Corp. Convair Div. to continue for 15 month contract now in force for launch support services for Atlas-Centaur launch vehicle. LeRC had management responsibility for Centaur. (NASA Release 68-8)
DOD announced termination of $175-million Mark 17 reentry vehicle program-for which $45 million had already been expended-"before additional R&D or heavy production costs are incurred." Funds originally designated for Mark 17 would be used for design changes on Mark 11. (DOD Release 43-68; AP, NYT, 1/14/68, 50)
Postdoctoral research opportunities under one-year research associate-ships to work in AFSC's laboratories and research centers would be offered by AFSC in 1968 and 1969. Awards would be made by NRC's selection board around April 1, 1968. (AFSC Release 4.68)
