From celebrity jets to Pelosi’s Taiwan trip, flight trackers are the sleeper hit of the summer

Forget Netflix: millions are now tuning in to watch little yellow plane icons move across a map of the world

Want to watch a top-secret government flight live? Track a drug kingpin's movements in real time? Or know how much Taylor Swift's jets are polluting the air? They're all streaming live on the sleeper hit of the summer: online flight trackers.

On Tuesday, viewers set new records on Flightradar24, one of the largest flight tracker websites in the world, as they watched the seven-hour flight of Nancy Pelosi from Kuala Lumpur to Taipei. The trip, shrouded in secrecy until its final moments, grabbed international attention after China made military threats in the weeks leading up to the visit, and then launched live-fire exercises once she had departed.
