LGW Vulture - well sport, for a supposed Senior Aviation Analyst, with regards to some of the stuff you contribute, you seem remarkably ill-informed (neigh, naive).
Accordingly I'd suggest you do a little more research as to the historic 'facts' in respect to the why's and wherefores of history of the Aberdeen Oil Contract work, e.g. it was the 'Oil Consortium' who wanted BWA to use (highly unreliable) ATP's (whereas BWA had wanted to use ATR's, i.e. they even had two of them on their AOC just for that purpose - and indeed a lot of the demise of BWA was due to a failure in refinancing / selling-on of the full-rate leases on the those two aircraft) plus the fact that to provide the required (contracted) 'service level' they needed to have a ridiculous number of (unreliable) ATP aircraft available, when two ATR's would have sufficed.
The bottom line is old son, there's a lot of history that surrounds all this, most of which you were not privy to !
Ps. It's for a good reason that the ATP is also known as, 'Another Technical Problem' - and in ALL of the above BAe have an awful lot to answer for (imho) !
