On September 21, 2025, the Honolulu Fire Department (HFD) received a 911 call at 12:49 p.m. and responded to a sick hiker on the Diamond Head Trail in Kahala with 6 units staffed with 17 personnel. The first unit arrived on scene at 12:57 p.m., established command and ascended the trail on foot. The next-arriving unit secured a landing zone nearby to prepare for air operations.

It was reported that an 84-year-old female was hiking, became dizzy and could not continue on her own. HFD personnel on foot arrived at her side at 1:08 p.m., performed a medical assessment, provided basic life support treatment, and prepared her for extraction. Air 1 lowered a rescue person to the hiker’s location where she was packaged and safely hoisted aboard the aircraft. Air 1 transported the hiker to the nearby landing zone, where her medical care was transferred to the Emergency Medical Services at 1:38 p.m.

All HFD personnel were accounted for with no reports of injury.
