I was spotting yesterday. KAL 249, a 74F made a very strange approach to JFK. She never overflew the CRI VOR for a 13L arrival,but flew over the Rockaways then passed over Rwy 13L and was sent to circle to make a VOR/DME 22L Approach. After finally landing, she did not move but I saw no Emergency trucks; any idea what happened? She was from ATL. The visibility was good. Arrival was 1444 EDT.
