I want your opinions please on this.
Is the UTTR (Dugway Proving Grounds) airspace more restrictive than the NTTR (Groom Lake area)?
I know the airspace within UTTR extends from Surface to 58000 feet.
Anyone can confirm this on which two airspaces are more restrictive than the other?
Ocassionally on www.planefinder.net, I see planes fly over the UTTR Dugway Proving Grounds area. But never over the R-4808N Complex NTTR airspace.
