Believe it or not...

Did you see the recent report on TV of the man (former stunt man, I understand) who shot himself a thousand feet or so into the air in a homemade rocket and lived to talk about it?  I thought the story was intersting in a 'isn't it crazy what some people will try for fun?' sort of way.  Then I heard his reason for the flight.  He wanted to prove that the world is flat (frisby shaped actually).  Isn't this kind of a giant step backwards in understanding how the earth and the whole solar system work?  Sadly, I don't think his experiment would show him anything but flat.  In my travels I've flown pretty high over various parts of this world, and the view to the horizon always looks flat, curved around the edges but flat. Oh my gosh, I've just described a frisby!! Relax, I still believe that the world is a big blue marble.
