METAR VNKT 032350Z 00000KT 0500 FG VV/// 08/07 Q1013
I just watched a replay of said flight (TK726, reg. TC-JOC) on flight radar.
It took off more or less on schedule at 1845z. Arrived near KTM at around the time of the metar above. Completed about ten holding patterns at FL210, then proceeded to KTM, made a go-around, tried for a second time and then ended up beside the runway apparently. "Landing" time at around 0200z, after two hours in the hold.
