Yes, the difference with this observatory is that it is mostly a private effort. We see these giant engineering projects from mainland people started with good intentions, yet how many have had problems and go bankrupt? TMT construction time is 8 years, a long time.The Air Force dome up on Mauna Kea now is empty. It was found to  have been turned into an orgy/party room with mattresses and all, bottles, trash.  That was a long time ago and has been cleaned up but its one of the inactive domes up there.What nobody is talking about is asbestos was used extensively as an insulator in the 60's, 70's, 80's, 90's.UHH has been dumped with the responsibility, and they don't have the money for asbestos removal.The Air Force dome might be the tip of the iceberg regarding how much asbestos is up there.Toxic cleanup is an issue.The sovereign issue is a diversion. This is ancestral burial ground and the existing observatories have failed to detail their close down cleanup plans for 2033.
