Flying a Drone Inside the World’s Largest Cave

BY Alan Perlman
20 March 2015

Ryan Deboodt, an aerial videographer, takes us on an otherworldly journey through Sơn Đoòng, the world’s largest cave, by both ground and air.

Located near the Laos-Vietnam border, Sơn Đoòng cave was only discovered in 1991. It wasn’t until 2009 that it was officially deemed the world’s largest. If you’re wondering why it took that long, I suggest picking up a copy of Blind Descent: The Quest to Discover the Deepest Place on Earth. It’s one of the most exhilarating books I’ve ever read and gave me an admiration for the amazing amount of logistics and psychological fortitude required to be a deep cave adventurer. Unreal.

Anyways, back to Sơn Đoòng. Ryan filmed the cave near its entrance and the first and second dolines (skylights), which are 2.5 and 3.5 km inside the cave respectively.
