Living and working in a busy town or city means you are pretty used to seeing and hearing airliners registered in many countries flying overhead. Flightradar24.com is a real time, flight tracking service which attracts 24 million visits each month. For me, even as a town dweller, I am in total awe of the sheer number of aircraft that take off, transit across cities, countries and continents and land without drama 24/7 whilst I work, sleep and play!
