G-ARUD msn 45160/754, was a
DC7C which Caledonian leased from SABENA (OO-SFD) to start the airline in November 1961. Returned to SABENA it was bought by Caledonian in early 1962 and was flying on a charter from the UK to South Africa as Caledonian 153 (I seem to remember it was a charter for Cyril Lord Carpets) when it crashed on take off at Douala, Cameroon on March 4 1962.
The accident was caused by a jammed elevator trim tab. The aircraft failed to climb and crashed into a swamp killing 101 passengers and 10 crew - the only fatal accident in the airline's history. see:
