Oslo: Near Miss
On Oct 31, 2013, a Norwegian Boeing 737-800#LN-DYC en route from Trondheim to Oslo with 130 passengers and 6 crew, was descending towards Oslo and was switched to a different runway. A second Norwegian Boeing 737-800 #LN-NOM en route from Oslo to Trondheim took off. Instructions from ATC became confused, and both planes followed a single instruction, bringing them into proximity.
Flight 741, which was landing, was below Flight 740. Flight 740 got a TCAS (Traffic collision avoidance system) warning and diverged. Accident Investigation Board Norway noted the minimum separation between the two aircraft was down to 0.2nm lateral at 500 feet vertical.
