Sixteen F-84G cerriers will be mainteined on Kwejelein, in order that a minimum of twelve will be operationel vor each test. Two B~29's or B-36's will be used as primery end elternete operetional command posts. Control ¢ these jet eirereft will be the responsibility of the project supervisor. the semples will be collected as high es possible end epproximetc ly one em 4 a helf hours after shot tine. To At zero tire, two of the spere jets will be in the shot ares, ready m4 perform reconnaissance es required to establish: a) vase of the upper cloud. dD) Lowest altitude of prominent features of the cloud creeted by wind shears c) Lowest eltitude at which e useful redietion intensity is present. This informetion will be reluyed to control eircraft end will be used to determine proper take-off time end flight altitudes for the twelve carrier Twelve F-84G circraft will constitute the semple collection teems. pilots will be exposed to cloud radiction. Twelve Col. Cerl Houghton of the project will provide the red-safety supervision of these pilots. Working time in the cloud will be reguieted by informetiom the pilot gathers from a wing tip ionizetion chember. This chember's metter will give the pilot an indication of perticulete semple strength thus far collectede /C
