would it not be preferable to keep the number of different types in the inventory down?
from the little i know it sounds the dauphins need a huge, huge amount of work. if they could somehow be brought up to date, refurbished and stripped of that heavy search radar for a reasonable price, then by all means put them in VIP service. the reduced weight on board would ironically make them more useful then when they were new.
as for embarassament? maybe it's something to do with the anecdotal stuff i've heard about them reaking of fuel inside, the seeming fact that they were overweight, overspecified and all in all - a wasted opportunity, we could of gone for pumas
