In 1997, Marine Sergeant Roderick Castle witnessed a massive, black triangular craft hovering near 29 Palms, California during a training exercise involving potential crash retrieval. His team was quickly detained by a group in black tactical gear while the object silently and rapidly departed, leading Castle to suspect it was an advanced, potentially alien-reproduced vehicle. Castle later attempted to share his experience with David Grusch, intending to testify before Congress about the incident and its implications for reverse engineering programs. This encounter adds to a growing body of UAP reports and suggests possible government involvement in studying and potentially replicating advanced aerial technology. The video seeks to connect this event to wider UAP research, including incidents at Aztec and Peru, and invites further investigation into the phenomenon.
