Test your skills as an air traffic controller by directing planes to their runways! But more than that, every game you play helps researchers at the Hybrid Systems Lab at Stanford and Berkeley collect data for air traffic control research. Contrails has been designed to collect information for scientific research as you play the game. This information is sent back to a server at UC Berkeley and used to reconstruct your game. Each game will be processed using machine learning algorithms to help learn models of controllers for air traffic control research. See the website for more details!
