You haven't missed much.
There haven't been any official updates in a long time. They basically have stopped providing updates and have stopped filing their financial reports. Also, a lot of company resignations have taken place this year. By my count, only three people remain: CEO Glenn Estrella, CFO Jeffrey Sawyers and GTC Pres. Dennis DeMolet. WSGI still owns GTC-USA, plus 2 million shares of TRKK (it's also possible that these shares were sold). As for any airships, who knows? There has been no information released about any airships. So we don't know whether any exist or have been tested. We don't even know whether the consortium still exists.
My assessment is that the company is pretty much on life support. There is still an enormous amount of debt, and little cash to do anything. I think we're either headed for bankruptcy or they will continue to do what they've always done over the years: NOTHING -- but exist.
