On December 27, 1968, North Central Airlines Flight 458 crashed into a hangar while attempting a night landing in poor weather at O'Hare International Airport in Chicago, Illinois, in the United States.

On December 27, 1968, the flight left Minneapolis on schedule at 4:15 p.m. Central Standard Time,[a] and made its intermediate stops without incident.

However, delays caused by weather and baggage handling meant that by the time the plane departed General Mitchell International Airport in Milwaukee at 7:48 p.m. CST for the final leg of its flight to Chicago, it was running 62 minutes behind schedule.

[2]: 3 At 8:14 p.m. CST, the aircraft began its approach to O'Hare, which had a 200-foot (60 m) ceiling with light rain and fog, and runway visibility varying from 2,800 to 4,500 feet (900 to 1,400 m).

[1] Its report, released on November 12, 1970, blamed the crash on "Spatial disorientation of the captain precipitated by atmospheric refraction of either the approach lights or landing lights at a critical point in the approach wherein the crew was transitioning between flying by reference to flight instruments and by visual reference to the ground.
