It's good to see everyone.
In terms of the empty planes, there are a couple of things to say.
There were a few empty planes that left the airports and only one of them was a Government of Canada plane. As mentioned earlier, the Shanghai airports, and all airports in China in fact, are extremely busy. On the weekend in question, there was a lot of bad weather going on, with heavy rain. Effectively what happened was the goods were unable to get from the warehouse to be loaded onto a plane in time for departure.
We have lots of planes lined up and obviously the empty plane was not ideal. Because of the rules around crew, in terms of managing their workload and time in the air, the carrier had to take off with an empty load. We've since had additional planes behind it, and we're getting ready to run about one plane per day in the near future.
Congestion at the airport, heavy rain and unfortunate circumstances is the short answer.
