) I take the joke ... but have to point out longevity is not the
same as reliability.

There may be a tenuous relationship in that something that has low
reliability may have a shorter than planned service life if a point is
reached where capital replacement is lower than maintenance (incl.
overhauls).

IOW is an artificial regime ... large fleet compared to traffic
requirements, unintensive service, very small dedicated operators as
