I would like to know where Tony Dixon, editor of Airliner World, got his information for the September 2010 page 83 review of ther ANRB. According to his editorial ""If connected to the internet, there are two choices: the ''network'' (ie what other users have picked up and have transmitted online) or what the individual aerial can see. For security reasons, the network data is delayed by 5 minutes (although for a subscription payment, this can be shown in real time). So what exactly is the subscription payment for?
