McKinleyville, Calif. -- At 10:45 a.m. Coast Guard Group Humboldt Bay received a "mayday" transmission from a 19-foot vessel in Arcata Bay. The vessel was reporting that a man on board was not breathing. Coast Guard Air Station Humboldt Bay diverted an HH-65C aircraft (CG6544) from a training mission to report to the bay to assist. Because of the aircraft's low fuel state a second aircraft was launched to assist. Upon arriving on scene, CG6544 lowered the rescue swimmer and EMT gear to assist with CPR and prepare the injured person for transport to the hospital. (Coast Guard video by Air Station Humboldt Bay)
