There are accounts of the US and other governments rushing to collect bodies and live ETs, not just ahead of inquisitive locals, but also ahead of ET craft that rush to crash sites and seem to search for survivors. And some say that the US and Russia discovered that at high power and certain wavelengths, early model radars could disrupt the navigation and control systems of UFOs.
Yet, to endorse your point, there are also indications that some seeming ET crashes leave craft that are unusually intact. As Jacques Vallée has argued, among other things, UFOs offer a mystery and a test of sorts. If the latter is true, I hope the ETs are both grading on a curve and that we are hiding our understanding from not just the public but from them as well.
After all, if David Grusch is correct about there being different types of ETs, then we cannot hope that all of them are benign.
Great post you have a good grasp of what is going on. The very fact that there are so many crashed vehicles lets us know just how much “traffic” there is here on earth.
