We were no. 3 when the THK was no. 1.
The wx was utterly benign. There was no ice.
Only thing we noticed was that it seemed ATC had packed too tight. Of course now we know the THK had slowed, so maybe that caused the no.2 to slow also, thus reducing the gap between us and the no.2.
After the no.2 was sent around we thought the problem was over as we'd have a decent gap now, but we heard ATC ask the no.2 if he'd seen anything on the ground which was a bit alarming. Shortly after we got sent round too.
Just posting events as we saw them. No idea of the cause. Never saw the Turkish.
