vtkInteractorStyleFlight: hack it to be usable?

Does anyone have experience using the vtkInteractorStyleFlight? It appears to not really work (no key bindings do anything) but the mouse click events will move the camera, you just cannot see where until you let off the mouse:

I’m wondering if there is a way I could at least update the renderer during the camera movement to be able to “drvie” the camera around the scene

And then I’m wondering if I could hack together a bunch of keypress events to trigger movements with the interactor so that I can use the keyboard.

Anyone of ever tried this? Or have another way to get the same effect of “flying” around the scene?
