Denver International Airport: Denver International Airport (DEN), (IATA: DEN, ICAO: KDEN, FAA LID: DEN) , is an airport in Denver, Colorado, United States.  At 33,531 acres (52.4 sq mi), it is the largest airport in the United States by total land area.  Runway 16R/34L, with a length of 16000 ft , is the longest public use runway in the United States.  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.  It also has the third largest domestic connection network in the country.  s of 2017 , the airport features 135 gates spread out over three detached, yet internally connected, linear concourses (A, B & C).

Continental Airlines Flight 12: 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."

Continental Airlines Flight 11: Continental Airlines Flight 11, registration N70775, was a Boeing 707 aircraft which exploded in the vicinity of Centerville, Iowa, while en route from O'Hare Airport, Chicago, Illinois, to Kansas City, Missouri, on May 22, 1962.  The aircraft crashed in a clover field near Unionville, in Putnam County, Missouri, killing all 45 crew and passengers on board.  The investigation determined the cause of the crash was a suicide bombing committed as insurance fraud.  The plane had been hijacked to Cuba the previous year as Flight 54.

Capital Airlines Flight 67: Capital Airlines Flight 67 was domestic scheduled passenger flight operated by Capital Airlines that crashed on final approach to Freeland, Michigan, USA, during a severe snowstorm on April 6, 1958.  The flight was en route from Flint-Bishop Airport to the Freeland-Tri City Airport (now MBS International Airport) when it crashed.  Flight 67 was the first of four fatal crashes in the space of two years involving Capital Airlines Vickers Viscounts; the others were Capital Airlines Flight 300 (May 1958), Capital Airlines Flight 75 (May 1959) and Capital Airlines Flight 20 (January 1960).

Northwest Airlines Flight 253: Northwest Airlines Flight 253 was an international passenger flight from Amsterdam Airport Schiphol in Haarlemmermeer, Netherlands, to Detroit Metropolitan Wayne County Airport in Romulus, Michigan, United States.  The flight was the target of a failed al-Qaeda bombing attempt on Christmas Day, December 25, 2009, in which a passenger tried to set off plastic explosives sewn to his underwear.  There were 290 people on board the aircraft—an Airbus A330-323E operated by Northwest Airlines, which had merged with Delta Air Lines the year before.  Had the attempt succeeded, it would have surpassed American Airlines Flight 191 as the deadliest aviation occurrence on U.S. soil and tied Iran Air Flight 655 as the eighth-deadliest of all time.  The incident was also the second in 2009 involving an Airbus A330, after the crash of Air France Flight 447 on June 1.  This was also the final accident/incident involving Northwest Airlines as it closed down a month later when it merged with Delta Air Lines.
