Hmm,
Hans asked.....
How
do you know from where the "lightning entered"? It is just as valid as
asking from where the current is coming when you light a light bulb with
a battery or "does the lightning strike down or up"?

Very
good question Hans, though not much relevance to the current, pun
intended, discussion. Common wisdom sez that electrical current flows
from cathode (-) to anode (+). For the answer to your question, your
favorite search engine can be of assistance.
