Seriouslyt hough it has always been easy to cause this sort of chaos and in fact in one way mobile phones (which can be tracked) have lead to the demise of payphones. Call an airport from a payphone round the corner of the other side of the country (or even in an other country) and keep the call short it will be traceable but you could be long gone . In a lifetime in telecoms was involved a few times in urgent traces of calls about bomb threats and you are 100% right -a lot of people get involved really quickly - and the idea that its alla wild goose chase appeals to some nutters ( english for psycopath)
