A drone flying near a major Taiwanese air base briefly grounded both fighter jets and passenger planes — a small incident, but a worrying one for an island already on edge about airspace security.

• A drone was spotted near the Ching Chuan Kang base in Taichung, forcing a stop to takeoffs and landings.
• Two civilian flights and eight military flights were disrupted before operations restarted about 25 minutes later.
• One inbound flight from Macau had to circle in the air until the base gave the all-clear.
• Police sent officers to the area but never found the drone or whoever was flying it.
• The case has been handed to aviation police, and patrols are continuing to hunt for the operator.

Outlook: Expect tighter drone patrols around Taiwan's military bases, with pressure on authorities to explain who was flying it and why.
