A little thread drift. Those who served in Changi in the late 1950's and early 1960's may be interested in this video of John Hutchinson's recollection of the Shackleton which came down off the Island of Borneo on 9 December 1958.
The Shackleton was powered by RR Griffin engines.

Hutchinson who was due to be part of the crew, by chance swapped with another RAF pilot because he had recently married and was house hunting in Singapore before his wife came out. In the interview he offers a theory as to why the accident happened.
