A drone flying into restricted airspace shut Taiwan's Ching Chuan Kang airbase for 20 minutes, an embarrassing security lapse for the air force at a time of rising pressure from China.

• Eight IDF fighter jets on night training had to land at Hsinchu airbase instead.
• A passenger flight from Macau circled for 20 minutes before it could land, since Taichung is a shared military-civilian airport.
• Airport staff switched on anti-drone measures, but the drone vanished before they worked.
• The air force has handed the case to aviation police and has not explained why jamming gear was not used.
• The lapse comes weeks after Taiwan's Han Kuang drills practiced exactly this scenario — drone defense and base protection.

Outlook: Expect tighter enforcement around Taiwan's military airfields and pressure on the air force to show its counter-drone systems actually work.
