Let's take Transport Canada as an example. They say that there were fewer accidents in 2008 than in 2007, but we don't know whether there were fewer flights. That statistic wasn't mentioned. I understand that you can take what's good from the statistics, but when the people were asked whether there had been a decline in air traffic, they didn't know. They provided us with documents, but I find that a bit strange. They told us there were fewer accidents, but they did not tell us whether there had been fewer flights that year than in previous years.
