Hi Arden, The NodeTrackerManipulator tracks nodes in the scene and creates a view matrix for the Camera to track it. It doesn't do exactly what you won't but the implementation might provide inspiration. The key bit is computing the transform of the aircraft and then camera relative to this, this combined matrix will be the inverse of the matrix that you want to apply as the Camera view matrix.
