Watching an aeroplane through a window

I was assuming that the travel was parallel to the window, in which case my triangles method is good enough.

If it were going into or away from the window, how would I go about it? I used to be pretty hot at transforming between different coordinate systems in 2d solid mechanics but dynamics was never my strong suit.
