Flying disc sighted near Hickam Field, Hawaii — oscillating white disc

On January 4, 1949 at 1407 local time, Captain Paul R. Stoney (1810th AACS Group, Hickam Field) observed an object initially approximately 25 miles east of Hickam, described as a large round piece of flat white cardboard oscillating continually with an extremely white underside and a dark non-reflecting topside. The object circled at approximately 3,000 ft, making right and left circles, gaining altitude, then departed climbing on heading 25 degrees magnetic. Speed estimated at approximately 85 mph. A secondary intelligence assessment suggested it may have been a piece of cardboard or lightweight material carried aloft by air currents over the cane fields near Hickam. Captain Stoney believed it was under absolute control at all times.

“The object appeared to be a large round piece of flat white cardboard, oscillating continually... extremely white on the underside, while the topside portion of the object seemed to have a dark, non-reflecting surface. The speed of the object was approximated at 85 miles per hour... it is the opinion of the witness that the object had limited maneuverability.”

Reported under Project SIGN. Observer is described as 'extremely cool and level-headed.' AACS intelligence assessment suggested possible cardboard/lightweight debris explanation based on local wind patterns. Duration approximately 28 minutes (1407-1435).
