TEST A: EXPLOSION IN AIR 



plane show her visible through the smoke cloud one 

 minute after Mike Hour. Much of the upper part 

 of her superstructure was missing entirely. A fire 

 was burning amidships. A minute later the fire ap- 

 peared to be growing in intensity and to be spreading 

 aft along the port side. Still later, the fire amidships 

 increased markedly, and the entire central section of 

 the ship was in flames. She began to list ; within four 

 minutes of Mike Hour she was on her beam ends. A 

 cloud intervened for a few seconds, after which she 

 was found to have rolled still further on her port side. 

 Her fires now appeared extinguished, but she was 

 settling fast. By six minutes after Mike Hour only a 

 small portion of her bottom was visible, and in another 

 two minutes she was gone. 



Divers later found her resting on her side in about 

 200 feet of water. They made an extensive survey of 

 her smashed superstructure and confirmed that much 

 of it was missing or unrecognizable. Her deck was in 

 very bad condition, and her shell plating also. 



The CARLISLE, an attack transport much like 

 the GILLIAM, sank within forty minutes. She too 

 was within one-half mile of the projected Zeropoint. 

 Divers found her lying nearly upright, with about five 

 degrees list to port. Her condition was generally sim- 

 ilar to that of the ANDERSON. 



The LAMSON, a 344-foot destroyer, located within 

 one-half mile of the projected Zeropoint, sank within 

 eight hours. Early photographs showed her listing to
