Of course they were both in active service then and I remember watching the Lightning do a supersonic pass with much joy. Off topic for a moment but, do you know perchance what's going to happen to XH558 at the end of this year? I've never had a chance to see a flying Vulcan, and it's too bad I won't ever get to see one (nor did I get to see the awesome display of both of he flight worthy Lancasters flying together last year...). 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. The point you raise is comparable to the fact that we'vve basically flown the life out of the last Avro Vulcan, meanwhile here in my home town we're still managing to keep an Avro Lancaster flying after all these years. Also, I realize anyone can infer where I live based on the statements in this e-mail, hah. Cheers, Christian -- Christian M. Gauger-Cosgrove STCKON08DS0 Contact information available upon request.
