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.

All in all, here is a presentation of how lightning strikes.
