Yes a direct hit should vaporize a spark plug. For a 100 kA hit two 1"
diameter rounded steel balls may survive.
Note that Ross Engineering uses carbon balls on their spark gaps.
At 50 kA/us every inch of wire will have a voltage drop of 500 to 1000
volts, so very short wires are in order. Wide copper straps having a
length-to-width ratio of 5:1 are good.
