Into the Air to Warn London of Air Raids 



Putting the bomb, or rocket in the 

 mortar. As is evident, the mechan- 

 ism for firing is simple. It can 

 quickly be mounted on the top of 

 a wall or on a convenient roof 



Fire! The operator simply pulls a 

 lanyard attached to the fuse and 

 away goes the bomb high over the 

 city. When many bombs are ex- 

 ploding the noise is deafening 



Cleaning out the mortar after firing. Since 

 the mortar is short, this is not difficult. Lon- 

 don plans to have smoke bombs for use 

 during the day, so that smoke clouds as 

 well as loud detonations may warn the people
