Bill Sweetman

Bill Sweetman is a British aviation journalist and author renowned for his expertise in military aircraft and black projects. He served as technical editor for Jane's Defence Weekly and Jane's Information Group, authoring three books on stealth technology. Key achievements include his 1992 investigation with colleagues into seismic evidence of sonic booms near San Gabriel Valley, California, suggesting a classified hypersonic aircraft like Aurora tested from Area 51, though denied by the US Air Force. He collaborated with researcher Nick Cook on Aurora rumors linked to advanced propulsion and WWII 'Foo Fighters.' Sweetman wrote 'Aurora: The Pentagon's Secret Hypersonic Spyplane' (1993), exploring connections to UAP sightings such as the 1990 Calvine, Scotland diamond-shaped object, often hypothesized as misidentified stealth craft like the F-117. His work bridges conventional black programs and unexplained aerial phenomena interpretations.
