After several years abortive searching for the last resting place of Viscount G-BFZL, I've just found it!
It enjoyed one of the most varied of Viscount careers, and flew with more Air Forces (four) than any other Viscount. It was also well known as a regular with British Midland, and Manx Airlines, and it was the last Viscount to operate schedules for Manx.
It was then sold for freight work in the Congo, and it is well recorded that it was lost in an accident when it attempted a three-engined take-off on a remote dirt strip in the Congo. However, given the remote and inaccessible location, I always suspected that it was likely to still be there, or most of it anyway, possibly re-cycled as local tin huts. But the location was not identified and I could find no further details on the web.
However, after another search today, and with many thanks to this Viscount website
