For LIKE shot, low altitude (400. feet) labeling of the air will be eccomplished with exploding mortar projectiles. ‘ihe distances from zero will be sim- iler to those of tne Wiancko gauges of project 6,1, Most of the mortars will be mounted on ten foot square rafts and placed in the legoon. The mortar produced puffs will be photographed by ten Wks “ab tem! 4 ‘ uitchell cameras ~ from vantage points on Engebi, Rojoa, Kunit, an rf Parry. In addition, the air will be labeled with smoke at ten altitudes above the bomb (5,060; 6,000; 10,000; 11,000; 15,000; 16,000; 20,000; 21,00; 27,000; 26,000 feet) by meens of bursting shells from gunse Will be glaced on Janet (Ln,eti), Signals furnished by E.G.&éG, by five Mitchell cameras from The guns All guns will be fired with timing The gun-produced puffs will be photographed the photo‘station on Ursula (Ro joa). for gInG shot, only the low eltitude (400) feet air lebeling technique will be used. Light mortars will be Placed on & line running epprox- inetely Lorthwest from ground zero, the nearest being at 4,000 feet and the most distant being et 15,900 feet. ‘he puffs will be photographed from Ursula, —,. 36 ee AH
