World altitude record 8365m ?

This flight was near Murmansk, Russia (GPS location is in the video, at the top point).

This place is very sparsely populated, there are no air routes, and there is no restriction on height for models.

Disclaimer: Here in the USA it would have violated the 400ft ceiling unless it had been an FAA authorized event.
