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) as well as co-founder and chief technologist of SIGHTER.io — an iPhone application for crowd-sourcing triangulation of UAP observations. For 20 years he was flight software systems director in The Aerospace Corporation's Space-Based Surveillance Division and worked as a consultant for NASA's Jet Propulsion Laboratory, where he built JPL's initial aerogel fabrication facility and served as principal investigator for the STARDUST Discovery mission's aerogel team.

• American mechanical engineer and UAP researcher
• Board member of the Scientific Coalition for UAP Studies (SCU)
• Co-founder and chief technologist of SIGHTER.io (crowd-sourcing triangulation of UAP observations)
• 20 years at The Aerospace Corporation as flight software systems director in the Space-Based Surveillance Division
• Consultant for NASA's Jet Propulsion Laboratory, built JPL's initial aerogel fabrication facility
• Principal investigator for the STARDUST Discovery mission's aerogel fabrication team
• Astrometric analysis of pilot sightings, notably the August 2022 Pacific incident involving five commercial airline pilots; member of Ben Hansen's expert team

For the UAP timeline, Buettner is one of the most active scientifically and methodologically working civilian researchers: his SIGHTER.io triangulation and astrometric analyses stand for the attempt to bring UAP data into science with genuine engineering methods — without slipping from the SCU framework into the fringe scene.
