Documented sightings reported in 2008.
Turkish security guard Yalçın Yalman filmed over two hours of high-resolution footage of disc-shaped objects off Kumburgaz between 2007-2009; TÜBİTAK's national research council analyzed the tapes and concluded the objects were not CGI or known aircraft.
Dozens of Texas residents observed a massive silent craft with military jets in pursuit, later confirmed by radar data showing the object near the presidential ranch.
