Well, I'm not a lightning expert, and all the talk about lightning
reminds me of a yiddish proverb. But the theory I've heard and understand
is as follows:
A grounded conductor aloft assumes the same potential as the ground it is
connected to. It therefore becomes difficult for it to build up a charge
and make it a potential target.
An ungrounded conductor aloft assumes whatever potential it wants. If it
is bombarded with rain, it picks up the charge of the rain. Wind friction
can also generate a sizable static charge. It may pick up enough of a
charge to become a target.
Of course, lightning is dumb, and it doesn't understand theory - it
strikes where and when it wants....
