A drone flying into restricted airspace forced Taiwan's Ching Chuan Kang air base to close, disrupting military training and one civilian flight — a sign of how easily a small drone can shut down a major base.

• A drone entered the airspace around the Taichung base, and the control tower shut the airport down.
• Eight IDF fighter jets on a night training run had to land at Hsinchu air base instead.
• A passenger flight from Macau circled in the air until the airspace reopened about 20 minutes later.
• The air force has handed the case to police to find whoever was flying the drone.

Outlook: Expect tighter drone monitoring around Taiwan's air bases, with pressure to explain whether this was a prank or something deliberate.
