Douglas J. Buettner

Douglas J. Buettner is an American mechanical engineer and UAP researcher who serves as a board member of the Scientific Coalition for UAP Studies (SCU) and co-founder and chief technologist of SIGHTER.io, an iPhone application for crowd-sourcing triangulation of UAP observations. He spent 20 years at The Aerospace Corporation as flight software systems director in their Space-Based Surveillance Division, overseeing software acquisition for multiple spacecraft payloads and space vehicle systems, and worked as a consultant for NASA's Jet Propulsion Laboratory (JPL), where he built JPL's initial aerogel fabrication facility and served as principal investigator for the STARDUST Discovery mission's aerogel fabrication team.

Buettner actively contributes to UAP research through scientific analysis, having conducted astrometric analysis of pilot sightings, notably the August 2022 Pacific Ocean incident involving five commercial airline pilots, and joined Ben Hansen's expert team for scientific analysis of UAP sightings, including a Connecticut police officer's viral UFO video. His work bridges engineering expertise with UAP studies through the development of SIGHTER.io to enable precise triangulation of UAP locations via crowd-sourced data, and he performed detailed analysis resolving the 2022 Pacific incident as potential misidentification, enhancing aviation safety while contributing to SCU efforts in rigorous, data-driven UAP investigation.
