Turkish Airlines aircraft is not moving but it is definitely not at the final parking position. There must be something with the jetway or something else. Ground control should not give the Asiana taxi clearance before its way is fully clear.
Interesting.
I see it this way: AN ATC Clearance to taxi doesn't always ensure that it is
clear to taxi. The Captain remains responsible for the safe conduct of flight. That includes taxying.....
Turkish stopped short of the parking bay for some undefined reason, tail still extending beyond the clearance marking [Yes, Istanbul has them]. Not an unusual occurrence. Asiana failed, again for some undefined reason, to see the Turkish aircraft and appreciate its tail infringing the safety marking.
In broad daylight, the Pilot[s] of the Asiana A330 collided with the stationary Turkish A321.
