Sai Gon Giai Phong Newspaper presents to readers pictures of the trip that are not ever made available to the public.

Most of them will be used to make a documentary film which will be broadcast on U.S. TV Natgeo channel produced by National Geographic.

A team of five divers, including three members of the rescue team who joined a search for local youth football team the Wild Boar trapped in Thailand's Tham Luang Cave last year, led by Martin Holroyd, a cave expert of the British Royal Caving Research Association, kicked off the research diving trip to look for a 600m river passage connecting Son Doong Cave and Thung Cave.

 

Experts believed when reaching a depth of 25m, the underground river section inside Son Doong Cave runs in connection with the underground river inside Thung Cave.

Divers went past a deep stop of 77 meters but they were unable to find the passage to Thung Cave and it went deeper underground.

Howerver,the team found a new tunnel system at a depth of 60 meters below present sea level. The exploration has clearly proved that Son Doong Cave is bigger than its current title of the world’s largest cave, making it more mysterious.
