RADIOACTIVITY VS. HEIGHT IN NUCLEAR CLOUDS 645 and Edward Fleming, Lawrence Radiation Laboratory, in directing and controlling the sampling aircraft contributed much to the success of the project. Our thanks are also due to Col. Templeton Walker, Commander, 9th Weather Reconnaissance Wing, and to all the members of the 1211th Test Squadron who displayed great enthusiasm and a high degree of professional competence in carrying out the sampling mis- sions.
