This NICAP-hosted file reproduces USAF Project Blue Book records on a radar and fighter intercept near Bellefontaine, Ohio, on 1 August 1952. Ground radar near Wright-Patterson AFB tracked an object moving at 400 knots. Two F-86s from the 97th Fighter-Interceptor Squadron were sent to intercept it and filmed a silver round object, but the gun camera film was too indistinct. The file includes a completed radar data sheet, a request from the Air Technical Intelligence Center, and a memo about releasing film frames to TRUE magazine. Early analyses ruled out a balloon, but a later conclusion identified the object as an upper air research balloon cluster.
