Question: What is the total land area of the airport at which the Continental Airlines Flight 1404 crash happened?

On 26 August 2017 a multiple-vehicle collision occurred on the M1 motorway near Newport Pagnell in Buckinghamshire, southern England.  The crash happened just before 03:15 BST (UTC+1), and involved two lorries and a Ford Transit minibus.  Eight Indians (six men and two women) were killed in the minibus and four Indians, including a five-year-old girl, were taken to hospital, three of whom had life-threatening injuries following the crash, which happened on the busy August bank holiday weekend. <SEP> Continental Airlines Flight 12, is a scheduled domestic passenger flight that on July 1, 1965 was operated by a Boeing 707 jet liner, registration N70773, 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 a.m. CST 1,100 feet down the runway.  Reverse thrusting and braking were initiated but did not slow the airplane 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." <SEP> Denver International Airport (DEN), (IATA: DEN, ICAO: KDEN, FAA LID: DEN) , is an airport in Denver, Colorado, United States.
