A special episode of the National Geographic series, Drain the Oceans, gives the most accurate rendering ever made of the escape route of the boys soccer team trapped in Tham Luang Nang Non cave in Thailand in July 2018.

Continuing Season 2,  Drain the Oceans: Thai Cave Rescue airs Monday, September 2 on National Geographic Channel.

Using using advanced mapping and LiDAR technology, the water is digitally drained from the flooded cave system. The special shows exactly how the group of 12 boys and their soccer coach were trapped, and why it took rescuers three weeks to free them from the extensive underground network.
