 Operations that use non-amphibious helicopters rely to a higher degree on hoists, rescue baskets, and rescue swimmers.Helicopters became frequently used, due to a number of advantages; they could fly in rougher weather than fixed-wing aircraft and could deliver injured passengers directly to hospitals or other emergency facilities.Helicopters can hover above the scene of an accident while fixed-wing aircraft must circle, or for seaplanes, land and taxi toward the accident.
