On October 29, 2025, the Honolulu Fire Department (HFD) received a 911 call at 9:53 a.m. and responded to a sick hiker on the Diamond Head Crater Trail with 5 units staffed with 14 personnel. The first unit arrived on scene at 10:01 a.m. and ascended the trail on foot. The second-arriving unit secured a nearby landing zone to prepare for air operations.

It was reported that a male hiker in his 60s became ill and was unable to descend the trail on his own. HFD personnel on foot arrived at the hiker’s location where they conducted a medical assessment and provided basic life support. The hiker was then escorted to a remote landing zone where he was loaded into Air 1 and safely airlifted to the landing zone. Medical care was transferred to Emergency Medical Services at 10:39 a.m.

All HFD personnel were accounted for with no injuries.
