Alien Reproduction Vehicle, a flying saucer made by the US military using captured alien technology.

Wow, so that was quite a false dichotomy being presented. Alien or alien clone (specifically the Area 51 craft, it appears), that's all you get to chose from.

Less than 5 months before his tragic death, Mark McCandlish delivered a final detailed, technical presentation on the legendary Alien Reproduction Vehicle (ARV) at the Alt Propulsion Conference. In a field crowded with rumor and recycled lore, McCandlish tried to do something unusually specific: treat the ARV story like an engineering problem—naming parts, proposing materials, describing electrical pathways, and arguing that multiple witness traditions converged on the same architecture. The result was less a "UFO story" than a guided tour through a speculative machine—one he insisted was reverse-engineered, human-built, and dangerously real.
