Just curious, how often does it happen? It's only the second time that I can remember this happening and it was about 10 or 15 years ago landing in DC that the landing was aborted.

We were coming in from Costa Rica a couple of hours ago and we were just about ready to touch down when the pilot gunned it and we circled around Atlanta. I can't remember exactly what the pilot said, but it was something about the plane in front of us...
