Robert L. Sieker

Robert L. Sieker is a figure associated with aviation archaeology and research into classified U.S. aircraft programs, with tangential connections to UAP/UFO discussions. No confirmed birth or death years, nationality (likely American), or primary role in direct UAP research are identified in available sources. He is referenced in contexts of aviation historian Peter Merlin's work on crash sites, including the XB-70 and D-21, where Merlin notes lessons applicable to UFO crash retrieval narratives, such as government cleanup claims. A memorial for Robert Sieker occurred on January 8, 2015, suggesting he passed away prior. No key achievements, publications, or testimony in UAP fields are documented. His name appears in discussions of secret programs like those at Area 51, but without substantive UFO involvement.
