BRIEFING ROOM AT KWAJALEIN. Briefing in 

 the well-appointed Operations Room of Task 

 Group 1.5 at Kwajalein was aided by the use of 

 maps and charts painted with fluorescent pigments 

 and irradiated in semi-darkness by ultra-violet 

 light. At the left of the central chart is a simu- 

 lated radar screen showing what the pilot will see 

 in his own radar screen as his plane approaches 

 its goal. During briefing each B-29, F-13, or C-54 

 plane's crew occupied a particular row in the 

 center section, seating being according to rank. 

 OPPOSITE. Experimental wing panels installed 

 by Task Group 1.4 personnel on the deck of a tar- 

 get vessel, to find the vulnerability of such panels 

 to atomic bomb explosions. Visible also along the 

 deck are a tail assembly, stablilizer, range-finder, 

 and rear support of a small mobile gun.
