The Germans Are Coming! Sound Bombs Soar Into the Air to Warn London of Air Raids
-
Caption 1: When air raiders approach London warning is now given by sound bombs which rise three hundred feet before exploding. Above is shown the mortar which is used for firing the rockets. They get results
-
Caption 2: Inserting the time fuse in a rocket before sending it aloft. The bombs produce a tremendous noise which can be heard over great areas. London has come to know this helpful "run to cover" signal
-
Caption 3: Putting the bomb, or rocket in the mortar. As is evident, the mechanism for firing is simple. It can quickly be mounted on the top of a wall or on a convenient roof
-
Caption 4: Fire! The operator simply pulls a lanyard attached to the fuse and away goes the bomb high over the city. When many bombs are exploding the noise is deafening
-
Caption 5: Cleaning out the mortar after firing. Since the mortar is short, this is not difficult. London plans to have smoke bombs for use during the day, so that smoke clouds as well as loud detonations may warn the people
