Pakistan.Karachi · four high objects with white trails cross the city

On the morning of Thursday, December 11, 1952, several people in Karachi, Pakistan, phoned or came in person to report that they had seen "flying saucers"; the file does not say to whom. An item the next day, with its source blacked out, pulled those reports together as "the consensus" of what had come in. By its account, scores of people in the streets saw four objects cross the city at about 8 a.m., very high and in parallel formation, leaving a white, smoky trail about 15 yards (some 14 meters) long. They disappeared toward an industrial district of Karachi.

Not everyone described them the same way. To some they were white metal discs, to others translucent circular objects; what they agreed on was the great height and speed. The same item offered a possible explanation: local authorities said that at about 7:30 a.m. four aircraft had flown over Karachi at a very high altitude, leaving vapor trails, and put that forward as the answer. At least one local reporter said the same thing: the so-called saucers were aircraft flying very high.

On December 12, the U.S. Army military attaché in Karachi sent Washington a wire summarizing the coverage. It placed the sightings between 7:30 and 10 a.m. and noted the reporter's version. The only source it named was Air Headquarters of the Royal Pakistan Air Force, which had replied that the witnesses' times did not match any high-altitude flight by its aircraft, jet or piston, in the Karachi area.

The report ended up in Project Blue Book, the U.S. Air Force's UFO files. The Air Force's technical intelligence center noted that further inquiry would follow if the information warranted it, but the press clippings cited were not with the report. On December 23, an intelligence summary from the U.S. Far East Air Forces, written in Tokyo, repeated the story in almost the same words. It placed the sightings, however, "between the hours of 00 and 10 AM." The same window, starting at 00:01, went onto the Blue Book record card, which closed the case as "insufficient data for evaluation." The file records no further action.

Nothing known about the sighting comes from a named witness. The description of the four objects is a summary, by an unidentified source, of reports that do not survive; the item does not say how many people called or whether anyone saw the objects up close. The military attaché in turn summarized the press. The file holds no signed statements, drawings or photographs, and the clippings that started the case never arrived with the report.

The authorities' explanation describes nearly the same thing as the reports: four objects, very high, leaving white trails over the city. The authorities put the aircraft at about 7:30 and the item puts the objects at about 8: half an hour between two rough times is not enough either to separate the two events or to join them. The Pakistani denial does not fully rule it out, because it covers only Royal Pakistan Air Force flights and says nothing about foreign military aircraft or airliners. Nor does the file include any schedule of flights over Karachi that day, so it does not show that anyone checked whether four aircraft really passed at that hour, or whose planes they would have been.

With papers that do not even agree on the time, the match with the aircraft can be neither confirmed nor ruled out. Blue Book's "insufficient data" verdict reflects exactly that: a case left where the first press item left it, with an explanation on the table and no one putting it to the test.
