Stringfield collected testimony from sources claiming knowledge of crashed UFOs and recovered non‑human bodies. He published a series of "Status Reports" detailing these accounts.

Stringfield served in the US Air Force and later worked in public relations. He was a director of the Mutual UFO Network.

Notable works: Situation Red: The UFO Siege, UFO Crash/Retrievals: The Inner Sanctum (Status Reports I‑VII)

Representative statement: Stringfield claimed that the US government has recovered multiple crashed UFOs and possesses non‑human biological entities.

Stringfield's work is foundational to crash‑retrieval lore. His sources are often anonymous, making verification difficult.

Stringfield is a key figure in UFO crash‑retrieval mythology, influencing later researchers like David M. Jacobs.
