MyPath was an Android application I worked on at Thales that allowed passengers to view their flight journey in a 3D environment. The app showed an airplane flying over points of interest along the flight path. The passenger could click on points of interest to view a fullscreen page with more details.
The 3D portion of the app was done in Unity3D by another developer, and the GUI overlay was done in Android. Eventually the Unity developer left the company and I picked up Unity in order to implement changes requested by the customer or to fix bugs.
