A closer look
Privacy is an absolute myth the second you cross the tarmac. Thanks to a technology called ADS-B (Automatic Dependent Surveillance-Broadcast), commercial aircraft constantly scream their exact GPS location, altitude, and speed into the open air to prevent mid-air collisions. Because these signals are completely unencrypted, a bunch of aviation nerds with cheap radio antennas routinely feed this data into public websites, meaning your paranoid mother can watch exactly how many times your plane circles O'Hare International before landing.
