Continental Airlines Flight 12, is a scheduled domestic passenger flight that on July 1, 1965 was operated by a Boeing 707, registration N70773, aircraft from Los Angeles International Airport to Chicago O'Hare International Airport with an intermediate at Kansas City Downtown Airport. After a routine flight the plane was making an approach on the instrument landing system for runway 18. There was heavy rain and low visibility at the airport. The wind was reported from the East-northeast at 7 knots. At most airports this would normally mean an approach should be initiated from the other direction, runway 36. Quality Hill in downtown Kansas City overlooks the airport from this direction. It is so close to the end of the runway that aircraft have to go around it to land safely in good weather. This obstacle prevented the installation of an instrument landing system on this runway. It is normally considered safe to land opposite direction in these conditions but they would be landing with a slight tailwind. The flight landed at 5:29 am CST 1,100 feet down the runway. Reverse thrusting and braking were initiated but did not slow the plane as anticipated. It began to veer 30° left before it ran off the end of the runway. The right wing impacted a blast mound as the aircraft rolled over it coming to rest in three pieces on the perimeter road between the mound and river levee. After an investigation the cause of the accident was determined to be "Hydroplaning of the landing gear wheels, which precluded braking effectiveness."
Although there were no fatalities in the accident it highlighted a number of shortcomings with jet aircraft operations at Kansas City Downtown Airport. At 7,000 feet, Runway 18-36 was barely long enough for 707 aircraft. The airport could not be expanded as it was surrounded on three sides by the Missouri river and a rail yard on the east side. In 1972 airline operations were moved to Kansas City International Airport.
Runway 18 and 36 are as of 2007 known as runway 1 and 19. Kansas City did not observe Daylight saving time until 1967.
