Plectron,
If it is age-related retirement from airliner cockpits, welcome to the club!
Personally, did less than 3 years on late-model Seven-oh (P2) and about 18 months P1 on the DC10-30. Both are superb aeroplanes, in terms of economy and basic concept. But both seemed a bit archaic, mainly in terms of systems (particularly failure-redundancy), by the time I got my hands on them.
Guess you could have mentioned 411A's Tristar, a more sophisticated aeroplane.
Plenty of scope for reading and discussion in the Aviation History and Nostalgia forum?
