Sir George Cayley,
They are indeed hoping to get longer distance flights and even trans-oceanic. I do not know how realistic that is, since SCQ is only 65km from there, but has only managed to attract one flight to Turkey, even if it has a 3200m runway.
I believe the pictures in Street View are old. I think the green poles before Rwy 21 are now part of the structure that supports the artificial reference surface for the radio-altimeter, which begins 400m before the threshold.
This can be seen in the Precision Approach Terrain Chart from the link below

I am now working abroad, but I will try to take some pictures next time I am around there.
