I have always been fascinated with that place.
From what I'm reading, at present, in order to play, all you have to do is somehow arrange air flight into TXO?
Not that anyone needs to be worried about me showing up; I shall have much better odds obtaining a ride on a space ship captained by My Favorite Martian, or Dr. Smith from Lost in Space.
But is that really all you have to do is fly in there? One certainly must have pre-arranged clearance to land. Surely there has to be more to it; One couldn't just get in a plane without any notice, fly over there, contact the control tower, and say, "I'm coming in" land and then go play. That seems ridiculous.
This sort of thing only increases the fascination for me about this place. Certainly an interesting history and future it has.
