Hi Henning,
Thanks for your comments.
It looks like they have corrected the altitude issue you mentioned in the Google 3D view. I set the Google 3D view altitude to around 39,000ft and moved the view point out to the east to pickup the inbound QF44 flight this evening. As you can see at the bottom of the image below, the altitude is 39,273ft and the ADS-B readout for QF44 was FL380.
