And I saw an Avro Vulcan flying this weekend, this year is the last time
that will ever happen. Two weeks before that I watched a General Electric
Lightning blast down a runway that I was standing right next to (it wasn't
allowed to take off). These are experiences that deserve the word "awesome?.
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.
