THE SALVO.
On the command " Fire", No1 pushed down hard on a lever. The
lever actuated first an external contracting friction brake, which locked the bearing setting securely. futher pressure on the lever
made contact with a plunger that completed the electrical firing circuit that sent the rockets on their way.
With a mighty Whoosh and a roar the roundshurled themselves
skyward. At the altitude set by the fuse the128 rockets exploded
more or less in unison to create a massive box of fire to the detriment of the German raiders and the joy of Londoners.
The sound made by the salvo was completely awe inspiring in its
noise and ferocity.
Personally I'd hate to be a civi hearing this for the first time, I wonder if they were trying to fire at a V1. Hence using this system instead of
simple guns. Fill the sky with metal and hope for the best.
