I'll start by saying thank you for your positive comments on the video. This was a video that was produced in-house by our experts with no outside help, so we're very, very proud of it.
In terms of the investigations we do, we investigate in aviation, rail, marine, and pipeline. In terms of how we compare with other countries, we are part of an organization called the International Transportation Safety Association, which is a body comprised of all of the independent investigative bodies. I would say that there are different models used around the world. We are probably closest to the Australian model.
Some investigative bodies, like the NTSB in the States, do road accidents. In Britain, for instance, they have three different models. So they have a different branch that does aviation, a different branch that does marine, and a different branch that does rail. Some in Europe and in the Far East are only aviation. So you have a mixture of different models across the world, but all of those bodies use the same methods and they follow the international protocols set down by ICAO in annex 13, which is what we follow at the TSB for all our aviation investigations.
I'm not sure if I've totally answered your questions, but....
