If they own the air above the private ground what happens when they use a helicopter to access public ground?
There used to be a rule that you could not hunt the same day you flew in, or there was a 24 wait from the time you fly in, until you can hunt. The land may not be allowed to be camped on overnight. I think the delay rule has been modified or changed.
I was just curious. I have seen multiple hunting shows do this and if they are willing to film it and show it it must be ok.
Flying in an aircraft operating at a reasonable altitude is a specific exception to trespassing in Wy (and probably every other state's) law. So you're fine from a trespass perspective - just fly in normally and land. You should now also be fine from a hunting regs perspective, but if you have any doubts call Game & Fish.
