Strange pyramid-shaped triangle craft captured over Jequitinhonha Valley, Brazil

The footage is reportedly said to have been recorded over the Jequitinhonha Valley in Minas Gerais, Brazil, in 2009 by an American tourist traveling through the region. According to the claim, it was filmed using a Sony DCR-PJ5 camcorder, a model advertised with 60x optical zoom and 1800x digital zoom. 

However, there is a significant inconsistency: the Sony DCR-PJ5 was introduced in 2011, making it impossible for that specific camera to have recorded footage in 2009. That said, the discrepancy could simply be the result of an incorrectly reported date or a mistaken identification of the camera model. If this is the only error, it does not automatically mean the footage itself is fake. 

After carefully examining the video, it appears to show what looks like a genuine triangular-shaped object rather than obvious CGI. The craft seems to have a bright light at each corner and a raised, pyramid-like dome at its center. 

Ultimately, there is no way to determine from the footage alone whether the object is a classified human-made aircraft or something of unknown origin. While its appearance is reminiscent of the alleged TR-3B, the design does not appear to match the commonly depicted TR-3B configuration.
