During a remarkable congressional hearing, former American intelligence official David Grusch revealed that the US government conducted a "multi-decade" programme aimed at collecting and reverse-engineering crashed unidentified flying objects (UFOs).
Grusch, who was in charge of investigating unexplained anomalous phenomena within a US Department of Defence agency until 2023, spoke before the House oversight committee in Washington, shedding light on the issue of alien life and technology, as reported by the Guardian.
It kinda sounded that people have gotten badly injured trying to reverse engineer this tech. Maybe its simply impossible with our current knowledge. Similar to that native village that build fake planes, fake air-towers and fake headsets after a visit from the modern world.
There was a theory i read a while ago based on some whistleblower reports that pilot and ship where one entity somehow and that the pilot was able to control things inside the ship from wherever they are. Same report also mentioned that spacetime works differently inside and is bigger similar to a Tardis.
I don’t believe this is all true, but if the truth is even slightly similar it comes as no surprise that we have not yet figured out how to replicate it.
