FAA Class G airspace (uncontrolled) is up to 1200 AGL almost everywhere except right near a controlled airport. I think there it is still 800 AGL. Pretty sure any saucer style vehicle would stay well below that as well as typical BDR rockets.

I commented on this when it was first announced and later defended by the company on TRF and YORF to a far lesser degree.
