This photograph was 

 taken by on automatic 

 camera mounted in a 

 drone plane flying di- 

 rectly above the Zero- 

 point at the instant of 

 detonation, a remarkable 

 achievement in drone 

 control. The cauliflower 

 is funnel-shaped at this 

 stage; within its jagged 

 rim is a condensation 

 cloud nearly a mile in 

 diameter, which evapo- 

 rated a few seconds later. 



In this oblique view the condensation cloud, still in an early stage, is 

 expanding on the heels of the air shock wave at over 700 miles per 

 hour. A large ship appears as a tiny black speck in the air shock disk, 

 the white area marking the outward sweep of the shock wave across 

 the surface of the water.
