From the final report on the NTSB inquiry into the August 2024 death of retired champion dirtbike/dirtroad car racer Scott Bloomquist, whose Piper J3 plowed into a barn: “The pilot departed from a private airstrip and overflew his property. The airplane subsequently impacted a barn adjacent to the airstrip. The airplane sustained substantial damage, and the fuselage was mostly consumed by the postimpact fire that ensued. The pilot was fatally injured. An autopsy of the pilot was performed by the William L Jenkins Forensic Center, Johnson City, Tennessee. The autopsy report listed the cause of death as blunt force injuries and the manner of death as suicide.”
Underscoring that summary, the report’s conclusion says the NTSB “determines the probable cause(s) of this accident to be: The pilot’s intentional flight into a building as an act of suicide.”
So it was a mini-9/11-ing. The barn did really burn from the crash. It wasn’t a controlled demolition.
