I was looking at this flight:
flightaware.com/live/flight/JBU4 … ogle_earth
in google earth and noticed the tracks were all in the ocean. I did a little digging and it looks like the gx:coord are malformed, per developers.google.com/kml/docum … ce#gxtrack. These should be space separated instead of comma separated. When I change the kml file myself, it renders ok.
I love flightaware, thanks for providing this awesome service.
