a 3,2 Flight Timea in Sampling Area Succeesful egampling requires that the aircraft have a flizht time capability long enough to permit radiation exposure to limit the duration of the mission. This condition was true only for wed Flight, The unforeseen operational limitation in flight timee mentioned in Lhe (FF tepeo Lin An weu otecunred . -LL Far. 1.2, abové, ardge because the,radar equipment in the control B-2y9 ° = gaxa—falso—b by, the cloudy weather which existed at the time of - gampling, As a reault, the sample control B-36 was directed to fly ve farther from the main cloud maes than it should have been.

In view of these consideratione, the F-84G air- craft in White and Blue Flights did not meet the requirement that they tave the capability of spending two hours in the sampling area. Cor- ty ective measures have been diacuseed with the Commander, TG 132.4.2, and it is believed that this condition will Lave been corrected by Zins Shot, . —_ ‘x qs 2 > Copled/DOE
