Seeing that the thread has already drifted, another engine-out take-off was designed for the Caribou by the first CO of RTFV, SQNLDR Chris Sugden DFC*. His concern was that an engine out landing might lead to an aircraft being left overnight in an insecure location, and lead to total loss before an engine change could be effected. He practiced the takeoff at Butterworth prior to deployment. As far as I recall, the technique was used only once in the field. It required a fairly long runway.
