No. There are very few countries that do it, but it's a good idea. We did have a safety inquiry in 1982, the Dubbin Commission of Inquiry into Aviation, which was not as extensive as my Dryden inquiry turned out to be. It came up with a number of good recommendations, some of which were implemented, but not all, by Transport at the time. It revealed a number of weaknesses in the aviation system.
When we got into the Dryden inquiry, we decided to do a system-wide investigation, and that took us away from what would have been an easy finding. I could have wrapped up that inquiry in one week by finding it to be pilot error, which was the traditional finding by accident investigators.
The pilot took off with ice on his wings, so that's pilot error. Obviously it is. But the reason behind that error was important. We therefore went into an aviation system-wide inquiry involving not only the pilots or air crew, but the air carrier, air carrier maintenance, all their policies, training policies, and management safety policies. We also looked into the involvement of the regulator, and we found a great many problems throughout.
