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

<P0-S0>  On the evening of December 20, 2008, the flight crashed while taking off from Denver resulting in 2 critical injuries, 36 non-critical injuries and a hull loss of the Boeing 737-524 aircraft. <P0-S1> Continental Airlines Flight 1404 was a Continental Airlines flight from Denver International Airport in Denver, Colorado, United States to George Bush Intercontinental Airport in Houston, Texas. <SEP> <P1-S0> 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. <P1-S1>  After a routine flight the plane was making an approach on the instrument landing system for runway 18. <P1-S2>  There was heavy rain and low visibility at the airport. <P1-S3>  The wind was reported from the East-northeast at 7 knots. <P1-S4>  At most airports this would normally mean an approach should be initiated from the other direction, runway 36. <P1-S5>  Quality Hill, in downtown Kansas City overlooks the airport from this direction. <P1-S6>  It is so close to the end of the runway that aircraft have to go around it to land safely in good weather. <P1-S7>  This obstacle prevented the installation of an instrument landing system on this runway. <P1-S8>  It is normally considered safe to land opposite direction in these conditions but they would be landing with a slight tailwind. <P1-S9>  The flight landed at 5:29 a.m. CST 1,100 feet down the runway. <P1-S10>  Reverse thrusting and braking were initiated but did not slow the airplane as anticipated. <P1-S11>  It began to veer 30° left before it ran off the end of the runway. <P1-S12>  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. <P1-S13>  After an investigation, the cause of the accident was determined to be "hydroplaning of the landing gear wheels, which precluded braking effectiveness." <SEP> <P2-S0> On 26 August 2017 a multiple-vehicle collision occurred on the M1 motorway near Newport Pagnell in Buckinghamshire, southern England. <P2-S1>  The crash happened just before 03:15 BST (UTC+1), and involved two lorries and a Ford Transit minibus. <P2-S2>  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> <P3-S0> Denver International Airport (DEN), (IATA: DEN, ICAO: KDEN, FAA LID: DEN) , is an airport in Denver, Colorado, United States. <P3-S1>  Runway 16R/34L, with a length of 16000 ft , is the longest public use runway in the United States. <P3-S2>  At 33,531 acres (52.4 sq mi), it is the largest airport in the United States by total land area. <P3-S3>  As of 2016, DEN was the 18th busiest airport in the world and the sixth busiest in the United States by passenger traffic with over 58 million passengers. <P3-S4>  It also has the third largest domestic connection network in the country. <P3-S5>  s of 2017 , the airport features 135 gates spread out over three detached, yet internally connected, linear concourses (A, B & C).
