Was monitoring the JFK tower feed a short time ago. Quite busy, but nothing too unusual except that within 30 minutes there were 3 go-arounds and 1 RTO (rejected take-off), none of which were related to each other and none due to equipment problems. Wx is/was 600' OVC and RVR 6000+ with light winds and light rain.
Doesn't speak too highly of pilot competency.
