So am I correct in my understanding - 'Spotters' use obscure (to the general public) aircraft tracking web sites, they spot a squawk that might have some emergency implication, they then post on obscure (to the general public) pilot & flying enthusiast web sites & then the families of passengers on that flight are scared by these sick purveyors of filth - because they happen to be reading these web sites - whilst their loved ones are in the air on flight numbers they know about?
Obvious innit.
