Gogo, the inflight Wifi company, has partnered with Watson and IBM's weather data to create a sort of automated Waze for Airlines. Say what? When the instruments on the planes in front of yours record turbulence, the data is uploaded and crossed with weather data on the fly. The result, if it is turbulence, can then be sent to your plane via the Gogo data connection. You get a re-route and the airlines save an estimated $100M a year.
What dataset or sets would you like to cross with some Ai to make something new? Link.
