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....
