On 1 February 1991, USAir Flight 1493 collides with a waiting SkyWest Airlines aircraft on the runway, killing 34 people. An air traffic controller mistakenly assigned the inbound Flight 1493 to land on a runway where SkyWest Flight 5569 was waiting to take off.

On 27 December 1991, Scandinavian Airlines Flight 751 crash-lands without loss of life in Gottröra moments after taking off due to both engines failing.
