Brad Sparks:

11:35-11:37 a.m. (EDT) USAF pilots Lt. Wilbert S. Rogers and Major Ezra S. Ballard flying in a T-33 at 20,000 ft from Dover AFB, Delaware, to Mitchel AFB, New York, on a NNE course at 450 mph saw a silvery metallic discus-shaped 30-50 ft object to their 11 o'clock position below their altitude viewed against the Sandy Point area and silhouetted against the ground. Rogers immediately turned left and descended to intercept the object which then banked, revealing its flat round profile, no appendages, no trail, and curved in more tightly on the turn than the T-33, covering an estimated 30-50 n. mi. in 2 minutes (about 1,000-1,500 mph), and seen projected against the ground near Red Bank and Freehold, New Jersey, as the T-33 descended to 17,000 ft, accelerated to 550 mph and covering about 120° of its 360° turn during the sighting. The object passed within about 8,000 ft distance of the T-33, descending from about 12,000 to 5,000 ft and headed at high speed out to sea near Pt. Pleasant at about 120° heading until disappearance.

Fran Ridge:

This case caused a major stir at the Pentagon. Radar case at Fort Monmouth preceded this incident. Before our our research efforts (T-33 pilot reports to the media) all we had was the GRUDGE Report and this final statement by Capt. Ruppelt: "The UFO that the student radar operator had assumed to be traveling at a terrific speed because he couldn't lock on to it turned out to be a 400-mile-an-hour conventional airplane. He had just gotten fouled up on his procedures for putting the radar set on automatic tracking. The sighting by the two officers in the T-33 jet fell apart when Metscher showed how they'd seen a balloon."  Brad Sparks analysis proves that the T-33 was NOT chasing a balloon. (See below).
