For those of us who have a pretty good idea of what's almost certainly left under that island, the comments on that FR thread are hilarious. (It's amazing, how far along the "knowledge curve" folks on this thread are -- compared to the FReepers who shun our work...
Guess I better put the details of the "Tennis Court" (and the bunker complex beneath it) aside for a bit, and share the evidence that LSJI shows almost no evidence of having "$29mm" spent on it to bury all those tunnels.
[Bottom line: almost NO dirt has been excavated or applied to that purpose. I.E., the tunnel complex is probably 95% functional.]

The tunnels are in a different location than the tennis court; the tennis court is a separate issue for which I’m inclined to believe the mountain was leveled and those variations arise mistakenly in some satellite imaging. It was “Q” that alluded to the tunnels being filled and there was reported activity on the island during prior time.
Don't you think that island has been guarded all along? It should have been, it's evidence-laden.
The tunnels were not filled. Additionally, it appears that it would impossible to get dredging equipment and some really difficult permits to fill the tunnels with the sand and coral from the local area.
So, they are probably completely functional.
Thanks for the ping.
