I know that I like the quiet of planes.  And I know I hate the noise of of people talking on their mobiles.  But I had never considered conference calls on a plane before.  Hell on earth.  Without the earth part.

Allowing people to talk on their phones in the air will turn a quiet flight into 6 hours of being trapped next to some guy on a conference call
