Fleet losses
ACW342, ref your quote "Unaware of any other aircraft fleet that ended service with no losses" in your #15, what about the RAF VC10 fleet?
In service for almost fifty years (1966-2014), with only two 'losses' - XR809 to Rolls Royce for the RB211 project, and XR806 damaged Cat 5 due to a grossly mishandled de-fuelling procedure by Brize's Eng Wing. Neither were in any way flight-related, so I submit that the VC10's 48 years of RAF service could be termed morally, if not factually, loss-free.
