Fluoroscent Photography Underwater

On a night dive in the Philippines several years ago, I had an opportunity to do a "fluoro" night dive. Atlantis Dive Resort rented blue underwater flashlights and yellow filter shields that went over divers' masks. Geared up, I set off into the night. The blue light was very dim and the dive was much darker than a normal night dive.

Four Heyphones - a specialist cave radio system that can transmit through hundreds of meters through solid rock - were relayed by the Police from Derbyshire to London Heathrow, to be flown out to Thailand by Rob Harper, Rick Stanton and John Volanthen

Thailand Cave Rescue: Brit cave divers report "gnarly diving"

The Cave

This cave system runs for many miles underground and is explorable from November to June. It is prone to seasonal flooding during the monsoon months: June to October. Apparently there are warning signs discouraging visits during the rainy season.

The moment the group are found

This is the transcript of the conversation between Rick Stanton, John Volanthen and the trapped children.

John: How many of you [are there]?

Children: Thirteen

John: Thirteen? Brilliant!

John: There's two of us.... we had to dive.

John: We're coming, it's ok. Many people are coming. We are the first.

Children ask what day it is

John: Monday. One week and Monday. You have been here 10 days. You are very strong, very strong.
