The public isn’t interested because it’s not news to them. The hearings show just how far behind the curve that congress is. Most of the UFOs are the result of black projects funded by the US taxpayer. The “tic-tacs” in particular are rumored to be products of Lockheed skunk works.
Those who were belittled for believing in UFOs are finally feeling a bit of liberation as what they have been saying is finally receiving attention. The deep state needs to make money, and they are starting to run out of wars as an excuse to keep their war machine running. Expect to see a fake alien invasion in the near future. But before the deep state can pull this off, they have to first start pushing the narrative that aliens exist, and could be dangerous.
