Another reason why it is exceedingly unlikely that the US or any other Earthly power has reverse-engineered crashed UFOs to obtain and utilize their ultra-advanced technology:
All it takes is to consider a good hypothetical analogy in Earth's technological/scientific history to see that there is not much chance for this scenario being true. One analogy would be, what if scientists in the year 2022 invented a time machine and (ignoring paradoxes for the time being) carried a couple of IBM main frame computers and a couple of PCs, back to the year 1780, and left them for the locals to examine. Even possibly, would the 1780 scientists and engineers be able to reverse engineer this advanced computer technology so as to actually duplicate it, produce it, and achieve supremacy over other powers in the 1780 world?
Consider what would be required. The 1780 scientists and engineers would, first of all, need to be able to see and examine the detailed structure of the microscopic and submicroscopic semiconductor devices in the large scale integrated computer chips, containing hundreds of thousands to millions of submicroscopic transistors , diodes and other devices. The problem is, that in itself (just the first step) would require much more powerful microscopes than the crude ones available at that time. In fact to see the actual submicroscopic structures would require electron microscopes, a technology nearly two hundred years more advanced and requiring a whole new physics (including quantum mechanics) to understand.
Even if they somehow developed high power optical microscopes able to partially image the devices, they would need to develop an understanding of the basic science underlying the microscopic physical structures they were examining, how they work, and the principles of how they work. As I mentioned, this would require along with a host of other things, the development of an understanding of quantum mechanics including its underlying mathematics.
Similarly, the 1780 investigators would need to examine, analyze, and understand the underlying logical design of the computers, the fundamentals of Turing machines which are basic to the technology, the fundamentals of computer programming, and a host of other areas involved.
I think the biggest barrier against the practical achieving of reverse engineering in this case would be that that the 1780 engineers would need to develop a, to them whole new, set of manufacturing technologies, even after having gotten over the hugely high hurdle of understanding the basic science and technology. Example: the high technology of manufacturing very high purity silicon wafers and the resultant large scale integration computer processors. They would first have to somehow determine the high purity level of the devices they were examining. Then they would have to develop the production technology to correctly dope the high purity silicon, slice it up into extremely accurately dimensioned discs, then emboss them with the vast numbers of microscopic gates, diodes, transistors, etc. and install leads and connectors. None of the necessary tools existed for this, or the tools to build those tools or the tools to build those tools, etc.
In Earth's history, this overall computer technology required great developmental effort for over a century, with each step needing to have been on top of the necessary foundation laid by the previous one. Like diodes and quantum mechanics leading to transistors, to miniaturization, to integrated circuits, to large scale microcircuits, and so on. Each step required tools that could only have been developed in the previous one.
Overall, what seems to me to be an impossible goal. It would still be impossible even if the year was 1870 - the level of their technology and science was still just too low.
A final observation: this hypothetical analogy is really probably a considerable underestimate of the magnitude of the problem, since the ETI technology exhibited by UFO vehicles is far more advanced over our own, than is our technology advanced over 1780 (or 1870) technology. The UFO vehicles' level of advancement is more like comparing our technology with the Stone Age.
