Rocket Lab catches, drops rocket booster with a helicopter in key reusability test

Small launch firm Rocket Lab USA Inc on Monday captured a falling rocket stage out of the air with a helicopter before dropping it in the ocean, appearing to achieve a partially successful test of the company's novel cost-savings approach to recovering used rockets for multiple mission to space. The demonstration, involving parachutes and a long cable hanging from a helicopter, sought to check off a key milestone for the Long Beach, California-based company as it ventures to slash the cost of sending things into space, an industry trend pioneered by billionaire entrepreneur Elon Musk's SpaceX.
