Well, that was some flying trip. Nancy Pelosi came and left Taiwan in less than 24 hours, departing to the sound of Chinese fury and an escalation of live-fire drills around the island. Whether the US Speaker was followed out of the skies by the Chinese with the same assiduousness that she was tracked on her way in is not known. But her flight into Taipei on a US Air Force C-40 caused quite a stir: 708,000 people tracked her flight using the Flightradar24 app.
