They are not balloons: -they move too fast and travel under water (as there were confirmed sonar hits of these objects). They are not conventional aircraft: -they have no wings or signs of obvious conventional propulsion. They were not false radar blips: -they were tracked on advance gun sight cameras including in both the infrared and high definition video modes. They were not camera software malfunctions -Because they were tracked on Navy ship radar, Sonar, Space based radar, and jet fighter radar.
These objects can do maneuvers that can’t be explain by our conventional physics because they defy our common understanding of inertia. This includes accelerating at extreme speeds, stopping on a dime, and changing directions instantaneously.
The real truth is the US government (and others) do know, and have known for decades, that these craft are extra terrestrial. In addition the US government has recovered and possible reverse engineered some of the technology behind them. This secret they believe is too large to let go of due to multiple military, social, economic and religious implications, none the less, it’s our responsibility to hold them to account and demand they tell the truth! Way too much is at stake to keep this all hidden any longer, it’s time for full UFO disclosure.
