Unfortunately not.
I want disclosure as much as the next guy. But I don’t think they will use a “batt to the face” method of announcing “oh, by the way. We have alien space craft and bodies.”
I suspect they will announce if they find microbial life in our solar system first. A bit more gentle approach.
If they do have craft, I think they’ve reversed engineered very little. It would be quite embarrassing to have alien craft and not be able to figure it out for your own purposes first.
