Interesting about the engines.
Dust over blades and wings can also generate a huge static charge.
Essentially one needs to match the voltage between two items that are otherwise insulated either by air or the tires. The same voltage matching is seen in high-tension crews working from helicopters or bucket trucks.
I have heard of crews letting the new guy go and grab a sling and get knocked on his butt by the electrical discharge to teach them about the importance of voltage matching before touching.
