David grusch claims double digit retrieved craft. Let’s figure these out

We have the most established included that would fit the traditional Lore are as follows,

Italy 1933

Roswell 1947

Some thing in the 50s that he didn’t disclose on JRE (guess??)

I seem to recall somthing crashed in Canada and was recovered with USA in the 70s.

Brazil 1996. Varghina Brazil.

Peru 1997 as per the infantry Kids interview with Greer ( I know, ew Greer. But I find it at least worth mentioning)

What else is there that even might fit. Anything documented throw it out.
