How friendly do you want those skies?
People are complaining about porn on airplanes that have Wifi. Flight attendants are the latest group to complain. Porn is a problem now there is wifi, but it was not a problem when people could play DVDs or load porn onto their lap tops? Are people different when they are really bored in the air? Are they willing to do things on impulse that they were not willing to plan for in advance? I do not think this is a good reason to get rid of wi-fi on airplanes. At best this seems like just an excuse.
