HIGH ALTITUDE VIEW, BAKER TEST. This almost 

 perfect birdseye view of the Baker burst was taken 

 from directly overhead by a drone photographic 

 airplane arriving exactly on schedule. To aid dis- 

 cussion of pictures like this, Task Force scientists 

 developed their own terminology. In this photo- 

 graph the rough central portion, or "cauliflower", 



is still in an early stage. Water which lay motion- 

 less a second before is now arising toward the 

 camera with the speed of a bullet, spreading 

 slightly as it rises. The surrounding white disc- 

 shaped area, concentric with the cauliflower, is 

 called the "fillet." It denotes the spread of the ex- 

 tremely intense pressure wave.
