Waiting for confirmation for that last one. Until then its just talk.
Sounds kinda farfetched. To claim to see something strange in the sky and study it is one thing, to claim to have access to special materials from the strange phenomenon and being able to duplicate it partnered with 2 well known companies is a whole another thing.
It doesn't sound far-fetched to me; it sounds like a logical development along this sequence: 1.) UFOs/AAVs are physical technology from other worlds, 2.) that technology has frequently been sighted and tracked in our airspace, 3.) at least one fragment of such a device has been recovered, 4.) the fragment can be analyzed and eventually reproduced to yield spacetime propulsion capabilities.
Note that the obstacle they're facing is in the reproduction of the material. That's not surprising - imagine if we had acquired a microprocessor at the turn of the 20th century: we would eventually have been able to figure out how it worked, but it would take decades of global infrastructure development to be able to replicate it. If they have recovered a piece of gravitational field propulsion material, it would make sense that we'd have a lot of infrastructure to build before we could replicate it - and that's exactly what they're saying in that Tweet above.
Lockheed and Boeing would be obvious partners for such a project - if I had a piece of alien tech and a basic understanding of how it opened up new field propulsion capabilities, that's exactly who I'd approach first.
Hopefully by episode six of unidentified, we'll finally get to see wth they're talking about with the materials analyses they've been so excited about. My take here is that this is all part of a long-term plan they came up with long before they launched TTSA, and the materials analysis of significance here is a reproduction of the findings they made under the auspices of the AATIP. I.e., they knew what they were going to find, and they planned on developing it from the jump.
Within the next five weeks we'll know if that interpretation of unfolding events is correct, or if I'm just wishfully thinking. But I don't tend to be a dewy-eyed optimist, so I think I'm reading this scenario fairly objectively.
Once in a great while, the world shifts beneath our feet: this may be one of those moments.
