The Honolulu Fire Department’s Air 1 rescue helicopter was called into action Saturday in two incidents involving hikers who ran into trouble on Oahu trails.

HFD received a 911 call at 4:33 p.m. reporting an injured hiker on the Mount Kaala Trail in Waianae and responded with six units staffed with 16 personnel. The first unit arrived on scene at 4:52 p.m., and secured a landing zone for air operations.

A group of four hikers, three men and a woman in their 20s to 40s, were hiking when one of member of the group was injured and unable to descend the trail on his ow, HFD officials said.

Air 1 dropped rescue personnel on the trail where they made their way on foot to the hiker’s location at 5:31 p.m.

The hiking party was escorted to the pickup point, where Air 1 safely transported the injured hiker to the landing zone, where his care was transferred to Emergency Medical Services at 6:16 p.m. The remaining hikers were taken to the landing zone, with the last one arriving at 6:28 p.m., HFD said.

Not too long after the first 911 call, HFD received another call at 4:50 p.m. reporting a stranded hiker above the Likeke Trail in Kaneohe.

Four units staffed with 12 personnel responded, with the first unit arriving at 5:03 p.m. at the Nuuanu Reservoir to establish a command.
