This is a sad thing. I have sympathy for the family and friends of the crew members. Unfortunately DOD branches are flying helicopters all around and all over the islands with increasing frequency, and with less aloha than in the past....lower elevations, closer to residential areas, and in greater numbers, I guess due to intensified training and war efforts. We all support that objective. But DOD should step back a moment from their daily routines, and take a look at the helicopter flight paths in relation to residential areas, and examine  what is probably a huge pile of noise and other complaints, about which we see and hear little or no change in flight courses or patterns. Service members sign up for these dangers, but we civilians, kids, frail elderly and tourists, do not expect to have risks from helicopters dropping out of the sky. On the windward side, Kaneohe, Kailua, Waimanalo there are frequent overland flights, not just the Marines, but others. We are tense and scared.
