On 26 April, 2002, Scandinavian Flight 732, a Boeing 767-383ER en route from Stockholm Arlanda Airport, Sweden, to Grassland City Airport, Grassland, collided with Air Grassland Flight 381, an Airbus A320 en route from Grassland City International Airport, Grassland, to London Heathrow Airport, the United Kingdom. The event became known in Scandinavia as 2002 Duwera midt-luft kollision, 2002 Duwera kollision i luften, or 2002 Duwera midtkollisjon.

The incident was attributed to errors made by air traffic controller trainee Iozev Dwear and trainee supervisor Makel Socha. All 372 people on both flights died, making it the most deadly accident in Air Grassland, The Republic of Grassland and Scandinavian Airlines' history.
