The whole UFO case report:
Francis Ridge:
There was a date discrepancy on this case. Ruppelt said it was the 12th and subsequently NICAP listed that date in The UFO Evidence. Project Blue Book, which didn’t list this as an ‘Unknown,’ showed it clearly as August 5, 6, and the documents (see below) show that this case as ‘unsolved.’ This incident always impressed me, and apparently it impressed a lot of others, too. For the die-hard skeptics at Project Blue Book this was the one they had always asked for. Here was a good UFO sighting. ‘This was an unknown, one of the best,’ a ground witnessed visual, with a ground radar tracking, and the pursuit of the object by a jet interceptor that also locked on with its radar, with all the maneuvers independently verified. The UFO was playing a cat & mouse game with an F-84 ‘Thunderjet,’  the first USAF jet fighter able to carry a tactical atomic weapon. Major Lawrence Tacker not only confirmed this case, but he wrote one NICAP member and told him the Air Force had gun-camera photos of the object and radarscope photos. (FSTS,243). Ellsworth AFB is located about 12 miles from Rapid City, and in 1947, the base hosted the 28th Bombardment Wing (BMW), flying the B-29. In July 1949, the 28th began conversion to the gigantic B-36 bomber. Ellsworth was one of the original five Air Force Operational Storage Sites for nuclear weapons, and first received its atomic bombs in 1952.

Joel Carpenter:
I've been checking on the model of F-84 assigned to SAC, and it turns out that the F-84G was the one based at Rapid City at the time. This was a tactical-nuclear-capable day fighter-bomber with straight wings and gun ranging radar. presents U.S. government (U.S. Air Force) documents that pertain to the UFO case.

The whole UFO case report:
Fran Ridge:
This is apparently case #15 of Major Dewey Fournet’s ‘motions study’ UFOs cases as presented to the Robertson Panel in January of 1953, whereby he deduced that UFOs were guided by intelligence and the flight characteristics indicated that the intelligence was beyond ‘us.’ It is also case #33, on the official clearance list. of 41 formerly classified Air Technical Intelligence UFO reports cleared for Maj. Donald E. Keyhoe by Albert M. Chop, Air Force Press Desk.

Dan Wilson:
At 3:13 p.m. eight military witnesses and radar confirmed the presence of two silver colored discs, estimated at 80' across, in the sky over Hamilton AFB in Marin County, California . The discs appeared to be dogfighting. They were joined by six other discs and formed a diamond formation. They sped away as USAF F-86 fighter jets were scrambled. The sighting lasted 75 minutes. This case is listed in the 1964 UFO Evidence, Section 11.” presents U.S. government (U.S. Air Force) documents that pertain to the UFO case.
