Inside Flightradar24, the website that tracks every plane in the sky

Flight-tracking websites follow the real-time movements of the more than 200,000 planes that take off and land every day. Following planes has become the internet's new hottest hobby, with Flightradar24 leading the way.
(CNN) — On an average day, more than 200,000 flights take off and land across the world. That includes commercial, cargo and charter planes -- which account for about half of the total -- as well as business jets, private aircraft, helicopters, air ambulances, government and military aircraft, drones, hot air balloons and gliders.
Most of them are equipped with a transponder, a device that communicates the aircraft's position and other flight data to air traffic control, and that signal can be captured with inexpensive receivers based on a technology called ADS-B, for Automatic Dependent Surveillance-Broadcast. That's what flight-tracking websites do in a nutshell, providing users with a real-time snapshot of everything that's in the sky (minus a few exceptions).
Researchers are uncovering deeper insights into how the human brain ages and what factors may be tied to successful cognitive aging ((is successful the best word to use? seems like we’ll all do it successfully but for some people it may be healthier or gentler or slower?)), including exercising, avoiding tobacco, speaking a second language or even playing a musical instrument.
