Every day, millions of aviation enthusiasts, frequent flyers, business travelers, and curious minds log into Flightradar24 to track aircraft in real-time. The basic (free) version is impressive, but anyone who has used it for more than a week knows the pain: the 5-second delay, the limited filters, and the dreaded "Upgrade to Premium" pop-up blocking advanced features like weather overlays and detailed aircraft history.

If you are a student in an aviation program (pilot training, air traffic control cadet, aerospace engineering) or a teacher preparing lessons on flight paths and airspace, you can apply for a free educational grant.

If you are serious about aviation and have a spare Raspberry Pi, an old computer, or even just a USB dongle, you can become a data feeder.
