Origin In March 2021, an online advertisement appeared to show an airplane and a train on an airport runway with steam pouring out of the train’s engine. The caption of the ad may have led readers to believe that the plane was about to hit the train. It said: “17 Airports With the Most Dangerous Landings in the World.” The online advertisement in question. It had all the makings of being a misleading photo. First, it was in an online ad, which often is notthemostreliable source of facts. The shadows looked too perfect. The light was bright and sunny. The grass was green and pretty. Perhaps it was from a flight simulation video game?
