FORECAST FOR BIKINI AND VICINITY. Major 

 Delmar L. Crowson, left, officer in charge of the 

 Crossroads Weather Central, Kwajalein, and Major 

 Paul L. Fackler, right, of the Army Air Forces 

 weather group, plot reconnaissance "tracks" or 

 courses to be followed by weather planes in their 

 daily flights out over the Pacific prior to Test 

 Able. Favorable weather conditions were abso- 

 lutely necessary before the day on which to con- 

 duct test could be decided upon. Actually Test 



Able was held on July I, the first possible date 

 set for the test; weather conditions predicted for 

 that day were ideal, and they were borne out 

 fully. On the day preceding Able Day, as well 

 as on Able Day itself, three especially significant 

 weather reconnaissance flights were made. Daily 

 weather conferences were held between forecas- 

 ters at Kwajalein and Captain A. A. Cumberledge, 

 USN, and Col. B. G. Holtzman at Bikini, aboard 

 "Mount McKinley."
