A six-minute video posted on YouTube has showed the journey of Good Morning America’s film crew inside "an extraordinary cave" deep inside a jungle of the central province of Quang Binh.
The scenes were shot from the Son Doong (Mountain River) Cave in Phong Nha-Ke Bang National Park and were broadcast to American viewers on Wednesday in the popular morning program on ABC.
The crew used seven Phantom 3 drone cameras to get aerial shots of the magnificent cave.
Ginger Zee, the host of the live broadcast, said the journey to Son Doong was the grittiest, most difficult and dangerous assignment she had ever been on.
The cave, which contains at least 150 individual grottos, a dense subterranean jungle, and several underground rivers became known as the world's largest cave in 2009.
