QUOTE: Originally posted by Overmod Zardoz -- my understanding was that if you were inside an electrostatically-charged Faraday cage and touched the wall, there would be little if any spark. Remember the formulas for charge distribution in a conducting sphere, and what the charge density INSIDE the sphere is? There might be some asymmetries in a metal cab that would allow small currents to flow -- but I'd expect these to be about on the order of the spark you'd get shuffling across a carpeted floor and touching a doorknob: high voltage, very low current. And, of course, not passing through the heart in the critical range of either current or voltage... Much more significant, I think, would be a strike introduced into the cab through some of the insulated wiring, which might allow very large current for a brief interval which would then happily discharge to the "Faraday cage." Randy! What's the breakdown voltage for the path between the engineer's hand and the most likely parts of the throttle control? ;-}
