Caledonian Airways DC-7C, G-ARUD
4th March 1962
In November 1961, a fledgling Caledonian Airways leased its first aircraft from Sabena, it was a Douglas DC-7C. She was registered G-ARUD and was named “Star of Robbie Burns”.
The aircraft went down into a swamp on the edge of a jungle on take-off from Douala, Cameroon, on March 4th 1962, with the tragic loss of all 111 passengers and crew.
The accident investigation was extremely thorough and was undertaken by the Directorate of Civil Aviation in Cameroon. The inquiry was held in Paris, Cameroon being a French colony at that time.
The highly skilled crew fought to save the passengers and aircraft, but where likely overwhelmed by a mechanical failure.
Here, we will recount the tragic event in some detail. Some of the information is empirical, though, using the original accidents reports, eyewitness accounts and research, I have interpreted these sources to provide what I hope is the most accurate and comprehensive record published of the accident that tragically cost so many their lives.
The account will stand as this site’s tribute to the passengers and crew of G-ARUD, their story is not forgotten.
A Summary of the Accident
On 1st March 1962 a Caledonian Airways DC-7C, G-ARUD, started out on a round trip charter flight (Flight CA153 / CA154) from Luxembourg to Luxembourg via:
Khartoum (Sudan),
Lourenco-Marques* (Mozambique) *now Maputo
Douala (Cameroon)
Lisbon (Portugal)
The charter was reportedly made by the Overseas Visitor's Club.
The flight timetable was as below:-
Luxembourg 01/03/62 Depart 22.12 Hours
Khartoum 02/03/62 Arrive 07.57 Hours
Khartoum 02/03/62 Depart 09:05 Hours
Lourenco- 02/03/62 Arrive 19:05 Hours
Marques 04/04/62 Depart 08:00 Hours
Doula 04/0362 Arrive 16:45 Hours
To the right is a map of Africa, showing the destinations G-ARUD did and was to call at.
Douala Airport in Cameroon had and still has a 2850 metre long runway; this is Runway 12 / 30. G-ARUD was using Runway 12 that night, taking off in a south south-east direction.
The first legs of the flight had passed without incident. After a technical stop at Douala, G-ARUD started engines at 18:02 hours and left the apron at 18:05 hours.
On reaching the end of 2,850 metre runway it waited for around 7 minutes in order to allow an Air Afrique flight to land (DC-4, F-BBDK). The DC-4 landed at 18:13 hours.
G-ARUD then lined up on Runway 12 and was heard to run up its engines up, this was to almost certainly to clear the engines spark plugs after idling for so long, it took off at 18:20 Hours. The Controller saw the aircraft lift off the runway, approximately inline with the Glide Path Transmitter, some 2400 metres after the release of its brakes. The Controller also noticed that the aircraft did not seem to have its landing lights on.
The Controller reported that it seemed to him that the aircraft gained height with difficulty and its anti-collision light was seen at low altitude before disappearing behind trees. The sky was then lit up by a fire.
The aircraft, flying over an area that was in complete darkness, struck a tree on the edge of a jungle with the port wing and left hand side of the fuselage. The first trees were struck at an altitude of 22 metres (72ft) above the threshold of Runway 30.
The aircraft went progressively into a dive onto its port wing over the next 130 metres, before crashing into a creek that runs through the jungle. The aircraft exploded, the distribution of the wreckage was mainly limited by the left bank of the creek, though the tail unit and starboard wing ended up on the right bank.
The creek is a tributary of the River Wouri and has a tidal range of 3 - 4 metres and it was at its high water mark.
Information on the DC-7C, G-ARUD
The DC-7C had been purchased new by Sabena in 1957 as OO-SFD, it was later leased out to Persian Air Services as EP-ADU, before being leased to Caledonian Airways and registered as G-ARUD.

The Inquiry was unable to establish exactly who was piloting the aircraft that evening as the controller’s radio traffic was not recorded at Douala. Though the Inquiry assumed that Captain Williams was in the Co-Pilots seat, Captain Frost was in the Pilots seat, Flight Engineer McArthur was at the Engineers Position and Francis Strong navigating.
The Inquiry's assumption on crew seating was based on the fact that Captain Frost was undertaking a routine Route Qualification flight under Captain Williams. F/E McArthur was the most experienced engineer and due to the night take-off, with a heavy load, the Inquiry assumed he was in the cockpit. The Inquiry established that all Crew held valid licenses and qualifications to operate the aircraft and that they had the average experience of a 4-engined aircraft crew at the time.
Weather Conditions
The weather conditions at Douala Aerodrome that evening at 18:20hours, when the aircraft took off were:-

The weather conditions at Douala Aerodrome that evening at 18:20hours, when the aircraft took off were:-
The terms are: Fc Funnel cloud, Sc Stratocumulus, Cb Cumulonimbus, Ac Altocumulus, As Altostratus
The Tower observed that there were Thunderstorms happening to the South South-East / South of the aerodrome.
Also scattered drops of rain were seen and it was a moonless night. Sunset was at 17.35 hours and there were 21 minutes of twilight that evening, after that it was dark.
The arriving Air Afrique DC-4, which landed at 18:13 hours, reported that there was significant cumulonimbus cloud (thunderstorm clouds) and heavy static in the south west, though the aerodrome was clear.
