'Helicopter Warfare' features daring helicopter missions and extraordinary personal bravery in treacherous environments.
Found this elsewhere
The series highlights the most daring helicopter rescue of the Vietnam War, where an unarmed helicopter used its rotary blades to cut down the jungle's 40-foot-tall bamboo and create a landing space to rescue 100 troops under-fire.
The series also features a courageous helicopter rescue during the Falklands War, which saved the lives of SAS members when their mission backfired due to a ferocious snow-storm.
There is also a helicopter rescue mission in the high altitude and dusty conditions of Afghanistan to find the lone survivor of a US Navy Seal team and a young Navy pilot who fights an enemy tank in the deserts of Iraq.
Hope that helps.
