[OT]Electronic Cams? EDN article Link

It's called a coffman charge. Not only was it used in W.W.II but early
British jet engines used this system of starting. The first time in the US
they went to start this British plane by hitting the coffman charge, which
by the way puts out thick black exhaust smoke and the ground crew not
knowing about the coffman charge promptly covered the air plane with fire
retardant foam.
