jfadool if the passenger was close enough to the current running through the skin of the plan (ie dozing with her head against the side) could she be shocked?
Very doubtful, If the passenger happened to be touching something metal with two different parts of his/her body like a head and a foot, or an arm and foot some current would go through them. But most of the current would still run through the plane, not the person.
Electricity like water flows through the least resistive path. Nice high quality aluminum is much easier to flow through than a person. So most if not "all" of the power would go through the plane.
Much like a bird sitting on a high voltage power line, it does have a very small amount of power flow up one leg, through its body, then back down the other leg. It's just so small in comparison to the amount of power flowing through the cable.
I was referring to the word "Grounded" which it clearly is not ;-)
Yep, not tied to earth ground at all.
