Laminar Research has released an update to its series of X-Plane flight simulator apps for the iPhone and iPod touch. The update adds a replay mode that is activated when the app is paused to allow users to view the last few minutes of their flight and provides higher-resolution maps, complete with buildings and airport runways. Other new features include new paint and increased detail for many of the aircraft, a more detailed lighting and fog model and an improvement frame rate, all contributing to a more realistic flight experience. X-Plane 9 is available from the App Store for $10 and is a free update for existing users. The other apps in the X-Plane series have also been updated with the same new features.
