Yes, as a matter of fact the new AWOS was developed by Nav Canada at our expense. We spent millions of dollars to do that in replacing the old legacy systems.
One place we tested it for a year and a half, which we had to do in order to satisfy the regulator that it worked, was Iqaluit on Baffin Island. We're quite comfortable with it. This is the best system in the world. We really developed it on our nickel, to make it happen.
