The sentiment resonates, but on the other hand I took a lot of video in those caves and it's all unwatchable, so I have enormous appreciation for what the BBC did. It's an incredibly hard environment to film in and I was absolutely amazed by the final product. Gavin Thurston rigged up cables from ice screws in the cave walls and set up a travelling robot camera thing he designed on it. There was a huge amount of equipment and hard work; for example for the crater shots I helped them carry up an enormous crane system to the crater rim which didn't even produce any useful footage. Also, the BBC guys were so charismatic that they could talk their way around rules and into places. For example, the helicopter pilots flying in the crater did things that aren't normally allowed. So in a way it's fake, but actually when it comes to the cave visuals, their work captures the feeling of being there, which otherwise I would never really be able to share with anyone. It really is an unbelivably spectacular place and almost impossible to film.
