If you have the Wolfram Alpha app installed on your iOS device, you can use it to tell you which flights are currently flying over your location. Simply type in “overhead flights” and it will give you a list of flights based on your geoIP. When you select a flight number, it will give you the origin, destination, duration, present flight speed, and more. If you’re one of the lucky ones with Siri, you can ask it to tell you this information too.
