In a special article for International News Service, July 29, CAA Radar Specialists James Ritchey (who tracked the unidentified targets both weekends) said that one of the airline pilots mentioned above got close to a UFO. "He reported to us that he sighted a yellow light that appeared to turn red and then back to yellow again, "Ritchey said. "The object appeared to be about two miles away and to be flying parallel with him. Radar confirmed that he was between two and three miles from the object." The Washington Post (July 28, 1952) reported that long range radar at Andrews AFB registered the UFOs from about 7:30 p.m. (EST) to about 11:00 p.m. (The CAA report on Washington radar sightings, although it has a column for that purpose, does not mention any Air Force radar sightings on either July 19/20 or July 26/27).

29	day	Washington, D.C.	Air Force called press conference on UFO sightings,
attended by more than 40 reporters. Suggested UFOs were probably temperature inversion or unexplained natural phenomena causing radar mirages, but announced USAF was calling in top scientists to evaluate sightings; setting up special grid cameras to determine nature of light from UFOs. Stressed lack of any menace to country.
29	noon	Los Alamos, New Mexico	Shiny, apparently metallic UFO watched by ground ob- servers through binoculars. Jet interceptors scrambled, observers saw UFO turn and move behind the jets.[17[

30	day	Washington, D.C.	International News Service reports:
"Radar experts and weather scientists today declined to endorse the Air Force theory that "flying saucers" are ground objects reflected in the sky under freak atmospheric conditions. (CAA radar men maintained that what they have seen were "unknown objects, 'twisting and swerving in an unexplainable pattern. . .A Weather Bureau official said that reflections due to such in- version ordinarily would appear on a radar screen as steady line, rather than as single objects such as were sighted on the airport radar scope."
