Funny I was discussing just this pair of planes last night - I last saw them fly in 1971 at RAF Shawbury. Of course they were both in active service then and I remember watching the Lightning do a supersonic pass with much joy.
Getting a little closer to the topic at hand, eventually parts will no longer be available for older computers so the decision will have to be made to either retire them or use more modern components to keep them going. Somewhat ironically the ones that can be maintained in ‘original' condition for longer may be the mechanical ones where replacement parts could be fabricated whereas valves and SSI TTL may not be able to be economically produced.
