HONG KONG — Midnight amendments to Cap 448G. Category C drones now cleared for flight—25kg to 150kg, insured to the teeth. The low-altitude economy advances. But over the border, silence. No special authorization framework. No bilateral air pact. The skies open—yet no legal bridge. Cross-border flights remain in legal limbo. More at 11.

HONG KONG, 24 APRIL — The ink still damp on Cap 448G’s expansion, and the first Category C drones—hulking 150kg beasts—lumber into test flights over Tseung Kwan O. Their rotors thrum with the weight of cargo, rescue gear, ambition. Insurance binders thick as ledgers, real-time geofencing logs streaming to CAD servers. But beyond the harbour, the mainland’s sky is a locked gate. No special authorization regime under the Chicago Convention. No mutual recognition of airworthiness. The sandbox hums—32 trials complete—but the bridge to Shenzhen remains theoretical. The Joint Lab with Qianhai is a gesture, not a treaty. Without an Unmanned Air Service Agreement, these machines are prisoners of the Pearl River Delta. Liability? Insurance covers damage. But which court judges a crash over the estuary? The silence is deafening. A full-scale integration waits on political will, not technology. The flight path is clear. The legal fog is not.
