Via the always excellent Maps Mania, we are referred to the rather infamous interactive flight tracker from Jack Sweeney that amalgamates real-time, crowd-sourced transponder data that follows commercial and
controversially the flight-plans of private jets belonging to well-known figures, the open-source forum used by other aggregators to publicise and monitor the itineraries and environmental footprint of celebrities who would rather their outsized impact, hypocrisy and whereabouts to be known. Some believe that keeping tabs on soi-disant free-speech champion Elon Musk motivated him to purchase Twitter and try to silence his critics. Taylor Swift also recently expressed feeling her privacy and security violated by Sweeney’s site—but in response sold one of her private aircraft, possibly for an upgrade. We were surprised to see the quite a number of smaller, non-commercial flights over our airspace. More at the links above.
