Question: On 2 October 1990, a hijacked Xiamen Airlines Flight 8301, collided with two other aircraft on the runways of the old Guangzhou Baiyun International Airport, while attempting to land, it was which type of short- to medium-range twinjet narrow-body airliner developed and manufactured by Boeing Commercial Airplanes in the United States?
Context: Guangzhou Baiyun International Airport or Pai Yuen Airport was the main airport in Guangzhou, China, until August5, 2004, when it was replaced by the identically named Guangzhou Baiyun International Airport, some 25 km to the north.  Opened in 1932, "Baiyun" means "white clouds" in Chinese, while the airport took its name from the adjacent Baiyun Mountain. On 2 October 1990, a hijacked Boeing 737, operating Xiamen Airlines Flight 8301, collided with two other aircraft on the runways of the old Guangzhou Baiyun International Airport, while attempting to land.  The hijacked aircraft struck a parked China Southwest Airlines Boeing 707 first, inflicting only minor damage, but then collided with China Southern Airlines Flight 2812, a Boeing 757 waiting to take off, flipping onto its back.  A total of 128 people were killed, including seven of nine crew members and 75 of 93 passengers on Flight 8301 and 46 of 110 passengers on Flight 2812. The Boeing 767 is a mid- to large-size, mid- to long-range, wide-body twin-engine jet airliner built by Boeing Commercial Airplanes.  It was Boeing's first wide-body twinjet and its first airliner with a two-crew glass cockpit.  The aircraft has two turbofan engines, a conventional tail, and, for reduced aerodynamic drag, a supercritical wing design.  Designed as a smaller wide-body airliner than earlier aircraft such as the 747, the 767 has seating capacity for 181 to 375 people, and a design range of 3850 to , depending on variant.  Development of the 767 occurred in tandem with a narrow-body twinjet, the 757, resulting in shared design features which allow pilots to obtain a common type rating to operate both aircraft. The Boeing 737 is a short- to medium-range twinjet narrow-body airliner developed and manufactured by Boeing Commercial Airplanes in the United States.  Originally developed as a shorter, lower-cost twin-engine airliner derived from the 707 and 727, the 737 has developed into a family of ten passenger models with capacities from 85 to 215 passengers.  The 737 is Boeing's only narrow-body airliner in production, with the 737 Next Generation (-700, -800, and -900ER) and the re-engined and redesigned 737 MAX variants currently being built. Guangzhou Baiyun International Airport (IATA: CAN, ICAO: ZGGG) is the major airport of Guangzhou, the capital of Guangdong province, China.  Both airport codes were inherited from the former Baiyun Airport, and the IATA code is derived from Guangzhou's historical romanization "Canton".  Baiyun Airport serves as a hub for China Southern Airlines, FedEx Express, 9 Air, Hainan Airlines and Shenzhen Airlines. The Boeing 757 is a mid-size, narrow-body twin-engine jet airliner that was designed and built by Boeing Commercial Airplanes.  It is the manufacturer's largest single-aisle passenger aircraft and was produced from 1981 to 2004.  The twinjet has a two-crew member glass cockpit, turbofan engines of sufficient power to allow takeoffs from relatively short runways and higher altitudes, a conventional tail and, for reduced aerodynamic drag, a supercritical wing design.  Intended to replace the smaller three-engine 727 on short and medium routes, the 757 can carry 200 to 295 passengers for a maximum of 3150 to , depending on variant.  The 757 was designed concurrently with a wide-body twinjet, the 767, and owing to shared features pilots can obtain a common type rating that allows them to operate both aircraft. China Southern Airlines Company Limited is an airline headquartered in Baiyun District, Guangzhou, Guangdong Province, China.  Established on 1 July 1988 following the restructuring of the Civil Aviation Administration of China that acquired and merged a number of domestic airlines, the airline became one of China's "Big Three" airlines (alongside Air China and China Eastern Airlines), the world's fourth-largest airline measured by passengers carried and Asia's largest airline in fleet size, revenue and passengers carried.  With its main hubs at Guangzhou Baiyun International Airport and Beijing Capital International Airport, the airline operates more than 2,000 flights to 208 destinations daily as a member of SkyTeam.  The logo of the airline consists of a kapok flower (which is also the city flower of Guangzhou) on a blue tail fin. China Southern Airlines Flight 3943 was a China Southern Airlines flight from the former Guangzhou Baiyun International Airport, Guangzhou to Guilin Qifengling Airport, Guilin, China on 24 November 1992.  It crashed on descent to Guilin Airport, killing all 141 aboard. The Boeing 777 is a family of long-range wide-body twin-engine jet airliners developed and manufactured by Boeing Commercial Airplanes.  It is the world's largest twinjet and has a typical seating capacity of 314 to 396 passengers, with a range of 5240 to .  Commonly referred to as the "Triple Seven", its distinguishing features include the largest-diameter turbofan engines of any aircraft, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone.  Developed in consultation with eight major airlines, the 777 was designed to replace older wide-body airliners and bridge the capacity difference between Boeing's 767 and 747.  As Boeing's first fly-by-wire airliner, it has computer-mediated controls.  It was also the first commercial aircraft to be designed entirely with computer-aided design. XiamenAir (formerly Xiamen Airlines) () is the first airline operated in the course of modern enterprise in China.  Established on July 25, 1984 and based in Xiamen, Fujian Province it operates scheduled passenger flights out of Xiamen Gaoqi International Airport and, to a lesser extent, Fuzhou Changle International Airport and Hangzhou Xiaoshan International Airport.  The airline is owned by China Southern Airlines (55%), Xiamen Construction and Development Group (34%), and Fujian Investment & Development Group (11%).  Xiamen Airlines holds a 99.23% stake in Hebei Airlines, 60% stake in Jiangxi Airlines.  By early 2014, the Airlines has set up branches in Fuzhou, Nanchang, Hangzhou, Tianjin, Changsha, and Beijing.
