This 82,000 square foot artwork transforms the airport floor into a spectacular sky. By inverting space to put the sky underfoot, it plays with the idea of defying gravity and evokes the wonder of flight. Crisscrossing this sky are a dozen ‘flight paths’ along which travelers can discover inlays of various airplanes and other things that fly, such as a satellite, helicopter and paper airplane. The central sky is encircled by a horizon featuring silhouettes of iconic Pittsburgh landmarks and neighborhoods.

In 2025, Merrell expanded the floor design into the new terminal. As arriving passengers cross the threshold of the new building, they also cross a horizon line within the terrazzo floor, stepping from the sky onto a reflection of the sky, with clouds mirrored in the surface of the water.
