Well I can tell you this. Theres a lot more then 3 airplanes taking off/Landing at any one time at a major airport during peak times. Tho this would have a lot of plus's to it, most of all no airplanes crossing runways and taxiways. And even more important, no vehicles. Just one vehicle making a wrong turn on to an active runway or taxi way can gumm up the schedule for hours.
Im just not sure this type of runway could handle the traffic tho.
