Absolutely. I mentioned this area because this area is already establishing some projects with Environment Canada because of the expected increase in aviation in high altitudes. We're establishing a project to have measurements of major emissions, particularly close to the layer we worry about--have planes follow the big 380 or 747 to look at emissions.
Because of the increased aviation across continents, it will have two things. One, it will reduce the distance between airplanes so they can examine the effect of the exhaust or the turbulence of one on the other. The other thing is, what are we putting in the atmosphere up there and how can we mitigate it? That's a major item.
The other thing is to work with companies like GE and others that produce engines to try to minimize emissions.
