 **Airplane Simulation Trajectory** is a WPF (Windows Presentation Foundation) 3D application that demonstrates the simulation of an airplane's trajectory over the ground. The application utilizes the [Helix Toolkit](https://github.com/helix-toolkit) (Helix3D) for rendering 3D graphics, providing an immersive experience of tracking the path of an airplane.
