Wow, how sad.  So many people dead for no reason.  This sounds just like a terrible accident to me, I mean they think it could have been caused by lightning striking?  What are the odds?  It's so sad when things like this happen that result in such a massive loss of life.  I feel bad for all the families affected and plus of course all the victims who lost their lives due to something so unnecessary.  Sometimes things like this just happen and there's nothing anyone can do to stop it I guess.
