Reef wrecks

Series 1 episode 3 is dealing with aircraft etc, I was surprised that the James Bond LCT and Vulcan which was built underwater with canvas and fibreglass mounted over a steel or aluminium framework, the outer covering has now gone just showing the remaining structure underneath and it shows them development and also shows them diving on the C-46,  landing craft tank and various other things, it’s fascinating to watch, I just thought I’d give you a heads up it is on Sky Nature HD 130 so it will on repeat on that channel at some point or they’re just normal Sky Nature.
