UNITARY-PIAN PROORAMl Detoili of Unitary Plan still guarded, but its general outline* revealed in various official documi including the recent Air Policy mission (Finletter) Report A< tag to this account, the plan ltd three separate research programs, calling for supersonic wind-tunnel'i structlon. These programs provide (1) 16 "small tunnels'1 to be built "universities and other educational itiiutions" throughout the country (2 new notional supersonic research cwii to be operated by NACA. with' "number of supersonic wind tunaflj somewhat larger than those already1 eriitencc*'and (3) another new centi uoder the U. 5.
