A system of airport runways with at least one runway 1 situated above ground, and at least one runway 2 situated largely below ground with entry and exit openings at either end 3. The subterranean runway tunnel has exit positions to minimise interference with other aircraft movements, and has a take-off zone 4 at either end to allow aircraft to use the runway in either direction. The underground runway is designed to reduce noise pollution during take-off, and reduce air pollution due to exhaust gases emitted during take-off. There may be an electronic guidance system within the tunnel to facilitate safe aircraft movement during take-off. The ground-level runway and subterranean runway may be positioned above each other, either parallel, parallel but offset, or at divergent angles.
