While living in Brazil, I was unlucky enough to experience two last-minute aborted landings. The worst of which happened when I was about to touch down in Rio.
It had been a very early start for me as I got the flight from Porto Alegre at around 6am and I spent most of the time sleeping uncomfortably on my window seat. I was so disinterested in being awake that I even chose to have another quick snooze even though I could see that we were fast approaching landing. I was half drifting off and contently expecting the landing at any moment when - WHOA - the plane sharply took off leaving my stomach on the runway strip. Now I was clutching the hand rest and fully awake! I think this may have been standard practice because there was no announcement and no look of panic for my fellow passengers. We then spent the next 15 minutes flying in circles until we finally made a safe landing. Pheuw. As I left the plane, I asked the attendant at the front what happened and she told me to wait there for a moment as she grabbed the attention of one of the pilots who was leaving as well. He told me that the landing was aborted due to a big gust of wind which came from nowhere and that he had to make a last minute decision. I then asked him, "so.... how close was it?" and he replied, "it was right at the critical moment" with a broad grin. I was a happy man stepping foot on solid ground after that experience.
