using again rnp procedures we can delink those airports so it doesn't matter to someone going into teterboro what's going on at newark and doing that today so we're seeing that type of delinkage in a number of airports around the country. and, you know, that's just one example. some of the optimized profile, the sense we are using today, dramatic savings in fuel. alaska airlines cites 60 gallons of kerosene every time they land coming down from alaska their high altitude approaches. they glide in. there's a tremendous savings, savings in fuel, emissions, noise, the noise footprint of people doing optimized profile descents, we can show you what goes on in louisville, kentucky, it's dramatic. so as we roll these out, it's not just a schematic anymore. these are real life operations and we deploy them as people get equipped and we get the procedures and training in place and as someone mentioned the momentum and pace is there and it will continue to accelerate. >> thank you very much. i look forward to the time we can talk more directly and thank the chairman and yield back. >> mr. kapuano. >>
