Ronald Johnson

Ronald Johnson was a 16-year-old Kansas boy who witnessed a remarkable event on his family farm on November 2, 1971, outside Delphos, Kansas. He saw a mushroom-shaped, glowing object hovering nearby, and when the object departed, it left a glowing ring on the ground. Johnson and his parents observed the object and its physical traces directly. The family examined the site promptly. The glowing ring resisted absorbing water and was analyzed by multiple laboratories.

The Delphos Ring case is considered one of the most important physical trace UFO cases due to well-preserved ground evidence and prompt investigation.
