Ronald Johnson

Ronald Johnson was, in 1971, a 16-year-old Kansas boy who, on 2 November 1971 near Delphos, Kansas, observed on his family farm a mushroom-shaped, glowing object hovering; after its departure, a glowing ring remained on the ground that resisted water and was later analysed by multiple laboratories. Thanks to well-preserved ground evidence and prompt investigation, the Delphos Ring case is considered one of the most important physical-trace UFO cases in history.

• 16-year-old boy from Kansas
• Event on 2 November 1971 on the family farm near Delphos, Kansas
• Sighting of a mushroom-shaped, glowing object hovering
• A glowing ring remained on the ground after the object departed
• Ring resisted absorbing water
• Laboratory analysis of the soil sample by multiple labs
• The Delphos Ring case as one of the most important physical-trace UFO cases; prompt investigation

For the UAP timeline, Johnson is the witness whose sighting produced one of the few serious physical-trace cases — the "Delphos Ring" remains a reference experiment around which laboratory debates on UFO chemistry keep flaring up.
