I once remember reading something to the effect of "Spantax loved their [990s] and held on to them for a long time" (probably here on the forum).
How was it possible for them to operate these jets for so long after most airlines gave up on them due to poor operating economics? It has been said that the 990 was a pilot's dream; the "Maserati of the skies" - and that alone would make for many good arguments in holding on to them. But as we know, maintaining aircraft is expensive; doubly so if they are older and not particularly efficient.
Another observation: these photos sure don't show the kind of thick black smoke that the 990 produced in older photos - did Spantax somehow modify the combustion chambers of the GE engines to make them comply with environmental standards that were already in place by the 80's?
