This is a very interesting and important early UFO case. It features an aerial encounter, "dogfight" maneuvers, rapid acceleration, and "evasive action". And if that's not enough, this report is Project Sign Incident No.207 (National Archives, Washington, D.C., Project Blue Book files) with no less than 27 pages of documents.

Nov. 18, 1948; Camp Springs, MD (BBU)
9:45-10:03 p.m. USAF Lts. Jackson and Combs, 2 reserve pilots, aboard an Andrews AFB T-6 aircraft traveling 150 mph and 2 independent ground observers saw a highly maneuverable whitish-grey oval lighted object smaller than the T-6 cross over Andrews AFB from NE to SW and back again in a circular pattern from 4,000 ft dropping to 1,700 ft then climbing to 7,000 ft. T-6 followed object to identify it, made 3-4 passes at the object while climbing, dove on the object at 240 mph but it dropped down and came up behind the T-6 and continued circling the base. T-6 was able with difficulty to put object in front of city lights on the ground to try to make out details, and came within about 300-400 ft turned on landing light and object responded with a dull glow, then sped off to the NE at 8,000+ ft and 500-600 mph disappearing. Object's speed varied from 80 to 600 mph in multi­directional or omni-directional flight, with vertical maneuverability, highly evasive with high acceleration. Another reserve pilot, a USAF 2nd Lt. in another aircraft over the NE corner of Andrews AFB at 1,000 ft saw the object directly overhead. A further independent witness, USAF Staff Sgt. John J. Kushner, observed object from the ground. (FOIA; Ruppelt p. 46)
