Did anyone see the pictures from Seattle showing a plane attempting to land yesterday in the storm. It was moving back and forth like crazy and just before it was going to land, the plane's landing was aborted and it quickly took off again. It was seconds from landing. It must of been terribly scary.

Have you ever been so close to landing and then the pilot aborted and then quickly went back in the air? Pilots, how would you know if it could be done safely and how is it communicated so quickly between the flight crew?
