1951·Mount Kilimanjaro, Tanganyika (today Tanzania)

Tanzania.Mount Kilimanjaro · metallic object over Tanganyika seen by an East African Airways crew (1951)

On 19 February 1951, the crew and the nine passengers of an East African Airways Lodestar out of Nairobi watched for about 17 minutes a bullet-shaped object with a fin at one end, some 10,000 feet above Mount Kilimanjaro, which then climbed and moved off eastward. The captain had the nine passengers sign a document stating they had seen it; Blue Book closed it for insufficient data and noted that the photos taken were not in the file.

Why: The only aircraft checked is a French Constellation, which the crew asked Nairobi about by radio as soon as the object was seen. Blue Book card: Nairobi was contacted to see whether the Constellation bound from Eastleigh to Tananarive, whose course was approximately that of the 'saucer', could be the object, and the only information gathered was that it was at about 17,500 ft; the press reported that, according to Air France, it would have been in the Kilimanjaro area at that time. But the card's conclusion is "Insufficient Data for Evaluation". (Project Blue Book — file “East Africa”, Feb 1951 (record card and report from the consulate in Dar es Salaam) ↗)

Project Blue Book, 'East Africa' file, 19 Feb 1951: ATIC record card and despatch of the US consulate in Dar es Salaam (3 pp.)

The Blue Book card (Project 10073 Record Card) records a 17-minute air-visual sighting by 'Crew and Passengers', an object 'like bullet with fin' heading east, and the conclusion 'Insufficient data for evaluation', with the comment that photos were taken but are not in the file. The despatch from the Dar es Salaam consulate to the Department of State (file 778.5612, February 1951), signed by Consul H. Gordon Minnigerode, reports that the crew and passengers of the East African Airways Lodestar watched the object for about 17 minutes above Kilimanjaro, through binoculars 'bullet shaped with a fin at one end' with 'three definite stripes', that Nairobi was asked by radio about the French Constellation from Eastleigh to Tananarive, and that the master obtained the signatures of the nine passengers. The passengers' names are blacked out in the copy.

The night in question

On the morning of 19 February 1951, an East African Airways Lodestar that had taken off from Nairobi at 7:00 with two crew and nine passengers (bound for Mombasa according to the Australian magazine that published the captain's account, and for Dar es Salaam according to the dispatch of the U.S. consulate in that city) was in flight when, at about 07:20, radio officer D. W. Merrifield drew the captain's attention to a bright object 'like a white star', motionless 'easily 10,000 ft' above Mount Kilimanjaro. The captain, Capt. J. Bicknell, studied the object in detail while the aircraft headed roughly towards it; the passengers took turns with a pair of field-glasses. The radio officer called Eastleigh, which suggested it might be a drifting meteorological balloon, a possibility Bicknell rejected after watching it for several minutes.

It was a metallic, bullet-shaped object which, by Bicknell's estimate, was over 200 ft (some 60 metres) long; the consulate recorded that to some passengers it looked 'like a bright star' to the naked eye and only through binoculars was its shape clear, with 'three definite stripes' along the body. At one end it had a square-cut vertical fin; its colour was a dull silver and, at regular intervals along the fuselage, it showed dark vertical bands. Bicknell insisted the outline was sharp and clean, without the slightest haze or blurring, which in his judgement ruled out a fuzzy atmospheric phenomenon. The object stayed completely stationary for about 17 minutes and then began moving eastwards, towards the coast, gaining height; according to the magazine account it was lost to sight before reaching 40,000 ft (about 12,000 metres), and Bicknell reckoned it covered 60 miles in three minutes, figures that are naked-eye estimates without measurement.

According to the consulate's dispatch, to make certain there was no mistake about the 'saucer', the master of the plane obtained the signatures of all nine passengers to a document stating they had personally observed it, which left a documentary record of the episode. The same dispatch reports that an American passenger took a picture, though the consulate could not reach him because he left for Zanzibar, and that another American shot some 30 feet of colour film. The photographic result, however, was disappointing: the Australian clipping in the file says the only public photograph showed a blurred spot, and that the film ('quite clear') was said to have disappeared along with its owner; the Blue Book card notes that photos were taken but are not in the file. This last detail, impossible to verify, became part of the case's folklore rather than of its evidential base.

The sighting took place at the height of the worldwide 1950-51 "flying saucer" wave and in the context of colonial British East Africa. The U.S. consulate in Dar es Salaam forwarded it to the State Department on 28 February 1951 as the first 'flying saucer' observed in East Africa, and Blue Book filed it with the conclusion 'Insufficient data for evaluation'.

Why it matters

The file handles two prosaic candidates, both aircraft: Eastleigh suggested at the time a drifting meteorological balloon, and as soon as the object was seen the crew asked Nairobi by radio about a French Constellation bound from Eastleigh to Tananarive on a course roughly that of the object, of which it learned only that it was flying at about 17,500 ft. That it looked 'like a bright star' to the naked eye and that the Lodestar was heading roughly towards it is consistent with a distant aircraft or balloon seen nearly head-on, which appear motionless for minutes. Against that stand the structured description (square-cut vertical fin, regular dark bands, 60 metres long, sharp outline) and the fact that eleven witnesses saw it, among them the captain and the radio officer.

The episode also serves as a methodological caution about photographic evidence. There were cameras on board and yet the result was a blurred spot; and the "clear" film that supposedly vanished with its owner is exactly the kind of unverifiable claim that inflates the legend without adding proof. This entry treats it as folklore, not data. It is purely visual, without radar or instrumented confirmation.

What's left on paper

Documented evidence

  1. Document signed by the nine passengers of the East African Airways Lodestar, at the captain's request, stating that they personally observed the object (U.S. consulate dispatch from Dar es Salaam, 23 Feb 1951).
  2. Prolonged daytime observation (~17 minutes) of the stationary object, initiated by radio officer D. W. Merrifield and confirmed by Captain J. Bicknell; to the naked eye it looked like a bright star.
  3. Structured description through binoculars: metallic bullet-shaped object, over 200 ft by Bicknell's estimate, square-cut vertical fin at one end, dull silver with dark vertical bands (the consulate records 'three definite stripes'), sharp outline.
  4. Final trajectory: climb and movement eastward, towards the coast; the 40,000 ft figure is the magazine account's estimate.
  5. Photographic record: according to the consulate, one American passenger took a picture and another shot some 30 feet of colour film; the Blue Book card says the photos are not in the file, and the only public photo remained a blurred spot.
  6. As soon as the object was seen, the crew radioed Nairobi about the French Eastleigh–Tananarive Constellation, on a course roughly that of the object, and learned only that it was flying at about 17,500 ft; Blue Book concluded 'Insufficient data for evaluation'.
