Flying has become much safer after Tenerife air disaster
The worst air disaster ever occurred on the runway of the airport on the Canary Island of Tenerife. Two Boeings collided there at full speed. One Boeing did not have take-off clearance yet, but other circumstances also played a role. It was very foggy and there was confused communication with the control tower. Since then, flying has become much safer. Airline staff are allowed to make mistakes and admit them, so that everyone can learn from them.
Once and for all: eradicating the yellow fever mosquito in Aruba

No (Golden) Grand Slam for Novak Djokovic
It was going to be the year of the Golden Grand Slam for tennis player Novak Djokovic, the No. 1 in the world rankings.

He won the first three grand slams, but during the Olympics he missed the boat, so a Golden Grand Slam was out of the question. A Calender Slam is still possible. Then he lost the US Open final and his dream went up in smoke.
