The teacher, 43, broke her right ankle about three-quarters into the four-mile trail and the student sprained her ankle halfway up the trail, said Honolulu Fire Department spokesman Capt. Richard Soo.

Fire rescue crews received the call for the injured student at 10:44 a.m. Another call for the injured teacher came in at 11:08 a.m. The trail was wet due to recent rains, but the trail is not considered a difficult one, Soo said.

The teacher and student were airlifted from the hiking trail, and then taken to the Kapiolani Medical Center at Pali Momi, Soo said. The student was treated and released, and the teacher requested no information be released, a hosptial spokeswoman said.

More than 100 seventh-grade students and chaperones from Kapolei Middle School were hiking the Aiea Loop Trail today, Soo said. Military from Camp Smith also helped in the rescue, Soo said.
