I wonder if anyone else thinks this rescue-event is suspect? Here's the film on The Guardian website of divers breaking through to boys. Convenient that it's an English-speaking rescuer with another diver offering translations. But more suspect seems to be the way the boys are posed so that all there faces are visible (like a team photograph.) Lots of military divers involved.
The Chilean miners event some years ago was also a hoax and this has a similar feel.
