Sea King ZA298 got mentionted “by name” (well, OK, serial number) several times, so I hope that it does eventually get preserved one day – the FAA Historic Flight perhaps?
After being shot down more than once, and still getting up to live and fight another day, ZA298 deserves to be spared, not reduced TO spares…

Oh, and the incident referred to in the programme was this one http://www.dailymail.co.uk/news/article-2084998/Royal-Navy-Sea-King-ZA298-war-downed-Taliban.html
ZA298 is up there with Chinook “Bravo November” as a long serving, long surviving chopper, and has earned a place in a Museum (FAAM perhaps?)
For a start, it’s ROYAL NAVY Historic Flight (I wish people would at least get the name right); secondly, there is very little chance RNHF will take delivery of a Sea King at any point. Let’s be sensible here, it’s tough enough keeping the existing fleet of (relatively simple) historic aircraft flying let alone add to it with a (relatively complex) aircraft like a Sea King.
But I feel sure ZA298 will ultimately find a good and suitable home.
