Though relatively new to the fight, helicopters have become an integral part of modern warfare. They scout enemy terrain, deploy soldiers into battle, fight off approaching foes, and save lives. Witness some of the most daring air rescue missions of the last half-century, featuring old, single-engine warhorses and high-tech wonders of ingenuity and design. We examine what made each chopper ideal for its mission and what made it vulnerable, through battle reenactments and interviews with the heroic pilots who flew into the face of danger.
