They won't disclose anything, the hawks are far too powerful. Whatever they release or allow to be "leaked" won't be the whole story or allow a full picture to emerge. All these psy-op guys like Grosch and Elizondo are either pawns or agents.
Nothing they've "disclosed" are new, it's all been rumoured about in the UFO community for years. The only interesting parts were the two videos from years back now....which raises even more suspicions.
Ultimately the strangeness in the sky and stories about the water will probably never be truly explained until nobody can make money from it anymore. From the "leakers" selling books to the aerospace industry getting massive research funding to "investigate" possibilities. It's still just a con.
