I can talk about the transport of dangerous goods and the air mode. As was explained before, carriers do have an SMS system in place where there's a component for dangerous goods.
The way the transportation of dangerous goods program works is we do targeted inspections of shippers and carriers, so we do an air mode kind of packaging inspection, because you realize that before being on a plane, a package will often be carried by a truck. So that's where we actually target inspection, and that's where civil aviation, under Martin Eley, the director general, who was here on Monday, will look at the SMS system, the safety management system, of a company like Air Canada and look at whether they have the proper component in place. We would do the targeted inspection at the origin, in terms of air.
