Found this on reddit (poster called Boulderrivers). It's a summary of Brazil's UFO congress which happened yesterday. It was a "show and tell" hearing to get people up to speed on the topic. As you can see, they were much more forthright and open than the US Congressional hearing.
The Official Night of UFOs in Brazil, May of 1986; at least 21 confirmed UFOs were seen and detected by military and civilians. Most were 30 meters in size, some were 100meters in size. One giant object was chased by a civilian aircraft controlled by an airforce colonel. The giant object was 1.5km in size. Armed jets were scrambled to pursue the phenomena which displayed intelligent behavior by avoiding the air fighters and inflicting interference with the controls of the jet. Airforce did a report and press conference about it, both available to the public. You can check a small documentary about it here; https://www.youtube.com/watch?v=HK4ea52uATU
The Colares Incident, officially called "Operation Saucer", 1977-78; Official investigation done by the airforce of phenomena that was attacking, marking and often killing civilians. Hundreds of confidential documents, pictures and at least a dozen of videos. Initially confidential, most of its contents were outed by the commander and whistleblower of the operation, colonel Uyrangê Hollanda in 1997 (who killed himself days after). The information he provided in 97 was confirmed in the 2010's by official disclosed documents under Brazil's Freedom of Information laws. You can see a documentary about the case here; https://www.youtube.com/watch?v=gUrxu2p8evMThere's also one of the interviews with the whistleblower; https://www.youtube.com/watch?v=p1aE5VRLaIc
The Acre Assault; 2014 wave of UFO attacks that occurred on indigenous tribes of the Amazon. One of the documents report a silver craft that landed in the center of a tribe and shot "lightbeams" that injured many and killed a pregnant woman. Investigations were done by the Polícia Federal (Brazil's FBI), and concluded that although they cannot confirm the veracity of the facts, the social and cultural effects it had on the tribes were so deep that changed their daily habits and rituals.

Fragments of the UFO were scattered all over the nearby beach and nearby houses/streets. Many were collected.

Such magnesium isotope would only be achievable naturally in obscene universal heat, such as supernovas. There are no means for it to naturally occur in the solar system.
