It's always worth looking at them on the WebTrak replay. On the evening of last December 15th there were 3 consecutive aircraft sent around on 09L, which is very unusual, though alas they have now scrolled off the end of WebTrak's 3 months' history.
Webtrak ? Is that still going ? Have you tried the later Aircraft trackers such as Casper or Planefinder.net, they have replays up to a year.
