现代奇迹 - Season 10 Episode 13 第 13 集
For over 20 years, the Black Hawk has been the U.S. Army’s front-line utility helicopter for air assault, air cavalry, and medical evacuation. The Black Hawk remains today the world’s most advanced twin-turbine military helicopter and flies wherever duty calls, from hot deserts to the icy Arctic. This is the dramatic story of how post-Vietnam, in the 1970s, the U.S. designed and built a new generation of sophisticated helicopters.
