I really should have paid less attention at school.
There, fixed it for you
The OP has obviously forgotten the days of the VC10, when the entire fleet could be spread across European cities at the same time. each in various states of repair. I seem to recall waiting for a VC10 from Akrotiri in the mid 90's, which went U/S. The replacement went U/S, and a third arrived with spares, only to go U/S and join the other two as 'apron decorations'.
