Yep Google Earth is very valuable for the impression, but less for the analytics. Plotting a cloud of dots in just 2D in LibreOffice or so, gives the analytics part. Just take care to handle the time axis properly, and you see many more aspects than in a fancy Google 3D view.

For example: Data points like the Long/Lat give a nice straight line (especially for the first half of the down to earth trajectory) with just one small "S-curve" in it. Practically suggesting, the chance, there are 360's involved is pretty low. And, these data points being subject to aliasing with a max cycle of 30 seconds based on a 50+ ton passenger aircraft movements, is also quite unlikely.
