Blue Book file, Rivera and Heaphy (CUFOS)

This file, from NICAP and CUFOS, collects US Air Force Office of Special Investigations records from 1949 on a Project Grudge special inquiry into a sighting at Rogue River, Oregon, on 24 May 1949. NACA Ames Laboratory employees Gilbert Rivera and Don Heaphy described a silvery pancake-shaped object about 30 feet across that sped off like a jet. An annotated analysis that follows rejects the radar kite explanation and concludes that the case must remain unexplained.
