MK Airlines Flight 1602 was an MK Airlines Boeing 747-200F cargo flight on a flight from Halifax Stanfield International Airport, Nova Scotia, Canada to Zaragoza Airport, Spain. It crashed on take-off in 2004, killing the crew of 7.It was the fourth accident for MK Airlines, as well as the deadliest.
The Boeing 747-200 was originally manufactured for South African Airways in 1980 as ZS-SAR, making its first flight on 24 October of the same year, and being delivered on 6 November.At some point during its service with SAA, ZS-SAR was converted to a freighter. On 11 November 1992, ZS-SAR was leased to Garuda Indonesia as 3B-NAS. Sometime before September 1995, the aircraft was returned to SAA, and in March 2000, was sold to MK Airlines as 9G-MKJ.
The captain was Michael Thornycroft, who had been with MK Airlines since its establishment in 1990. He had 23,200 flight hours including 4,000 hours on the Boeing 747. Thornycroft also had dual South African-United Kingdom citizenships. The first officer was Gary Keogh, who had 8,537 flight hours and was described as a "competent" pilot and was "comfortable" with computers. The flight engineer was Peter Launder, who had 2,000 flight hours. There was also a relief captain and flight engineer. The relief captain was David Lamb, and the relief flight engineer was Steven Hooper, who had 1,600 and 1,990 flight hours respectively. : 4–6 The ground engineer was Mario Zhan, who held dual South African and German citizenships, and the loadmaster was Chris Strydom. Six of the seven crew members were from Zimbabwe; the seventh (Captain Thornycroft) was from South Africa.
At 00:03 local time, on 14 October 2004, MK Airlines Flight 1602 took off from Windsor-Locks-Bradley International Airport. The aircraft was loaded with a cargo of lawn tractors, and made an intermediate stop at Halifax at 02:12 to be loaded up with approximately 53,000 kilograms (53 t; 117,000 lb) of lobster and fish.
Flight 1602 taxied to Runway 24 (now assigned '23' designation), and the takeoff roll was commenced at 06:53:22. When the aircraft reached 130 knots (150 mph), the control column was moved aft to 8.4° to initiate rotation as the aircraft passed the 5,500-foot (1,700 m) mark of Runway 24; with 3,300 feet (1,000 m) left on the runway, the aircraft began to rotate. The pitch attitude stabilized briefly at approximately 9° nose-up, with an airspeed of 144 knots (166 mph). Because the 747 still had not lifted off the runway, the control column was moved further aft to 10°, and the aircraft responded with a further pitch up to approximately 11°; at this time, a tailstrike occurred. The aircraft was approximately at the 8,000-foot (2,400 m) mark and slightly left of the center-line. The control column was then relaxed slightly, to 9° aft. The pitch attitude stabilized in the 11° range for the next four seconds, and the tailstrike abated as a result. With approximately 600 feet (180 m) of runway remaining, the thrust levers were advanced to 92% and the engine pressure ratios (EPRs) increased to 1.60. With 420 feet (130 m) remaining, a second tailstrike took place. As the aircraft passed the end of the runway, the control column was 13.5° aft, pitch attitude was 11.9° nose-up, and airspeed was 152 knots (175 mph). The highest recorded nose-up pitch of 14.5° was recorded at one minute and two seconds after takeoff initiation after the aircraft passed the end of the runway at a speed of 155 knots (178 mph). The aircraft became airborne approximately 670 feet (200 m) beyond the paved surface and flew a distance of 325 feet (99 m). The lower aft fuselage then struck an earthen berm supporting an instrument landing system (ILS) localizer antenna 300 metres (980 ft) beyond the end of the runway, separating from the plane. The plane then headed forwards in a straight line for another 1,200 feet (370 m), breaking into pieces and bursting into flames when it struck the ground.

An investigation into the crash revealed that the flight crew had used the incorrect speeds and thrust setting during the take-off attempt, with incorrect take-off data being calculated when preparing the flight (incorrect V speed calculation, as the result of the crew re-using a lighter take-off weight of 240,000-kilogram (530,000 lb) from the aircraft's previous take-off at Bradley, instead of the correct weight of 353,000-kilogram (778,000 lb). The official report blamed the company for serious non-conformances to flight and duty time, with no regulations or company rules governing maximum duty periods for loadmasters and ground engineers, resulting in increased potential for fatigue-induced errors.
MK Airlines disputed the findings, citing the fact that the cockpit voice recorder (CVR) was too heavily damaged in the post-crash fire to yield any information.

China Airlines Flight 611 was a regularly scheduled passenger flight from Chiang Kai-shek International Airport in Taiwan to Hong Kong International Airport in Hong Kong. On 25 May 2002, the Boeing 747-209B operating the route disintegrated in midair and crashed into the Taiwan Strait, 23 nautical miles northeast of the Penghu Islands, 20 minutes after takeoff, killing all 225 people on board. The in-flight break-up was caused by improper repairs to the aircraft 22 years earlier. As of 2021, the crash remains the deadliest in Taiwanese history, as well as the most recent accident of a 747 involving passenger fatalities.
China Airlines Flight 642 was a flight that crashed at Hong Kong International Airport on 22 August 1999. It was operating from Bangkok to Taipei with a stopover in Hong Kong.
Japan Airlines Flight 123 was a scheduled domestic Japan Airlines passenger flight from Tokyo's Haneda Airport to Osaka International Airport, Japan. On August 12, 1985, a Boeing 747SR operating this route suffered a sudden decompression 12 minutes into the flight, and crashed in the area of Mount Takamagahara, Ueno, Gunma Prefecture, 100 km from Tokyo 32 minutes later. The crash site was on Osutaka Ridge, near Mount Osutaka.
MK Airlines Ltd. was a cargo airline from Ghana, which was operational between 1990 and 2010, concentrating on freight services to and from Africa. The airline routed most of its transported freight via its European bases at Gatwick Airport, Kent International Airport, Ostend–Bruges International Airport or Luxembourg-Findel International Airport. The African hub was located at OR Tambo International Airport, serving Johannesburg.
United Airlines Flight 811 was a regularly scheduled airline flight from Los Angeles to Sydney, with intermediate stops at Honolulu and Auckland. On February 24, 1989, the Boeing 747-122 serving the flight experienced a cargo-door failure in flight shortly after leaving Honolulu. The resulting explosive decompression blew out several rows of seats, resulting in the deaths of nine passengers. The aircraft returned to Honolulu and landed with no further incident.
Pan Am Flight 845 was a Boeing 747-121, registration N747PA, operating as a scheduled international passenger flight between Los Angeles and Tokyo, with an intermediate stop at San Francisco International Airport. On July 30, 1971, at 15:29 PDT, while taking off from San Francisco bound for Tokyo, the aircraft struck approach lighting system structures located past the end of the runway, seriously injuring two passengers and sustaining significant damage. The crew continued the takeoff, flying out over the ocean and circling while dumping fuel, eventually returning for a landing in San Francisco. After coming to a stop, the crew ordered an emergency evacuation, during which 27 passengers were injured while exiting the aircraft, with eight of them suffering serious back injuries. The accident was investigated by the NTSB, which determined the probable cause was the pilot's use of incorrect takeoff reference speeds. The NTSB also found various procedural failures in the dissemination and retrieval of flight safety information, which contributed to the accident.
The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the earth's atmosphere. It helps maintain pressure when stratocruising and protects the aircraft from bursting due to the higher internal pressure.
The article describes accidents and incidents on Korean Air and its predecessor companies Korean National Airlines and KAL. Korean Air had many fatal accidents between 1970 and 1999, during which time it wrote off 16 aircraft in serious incidents and accidents with the loss of 700 lives. The last fatal accident, Korean Air Cargo Flight 8509 in December 1999 led to a review of how Korean cultural attitudes had contributed to its poor crash history. Since then safety has improved.

As of July 2020, a total of 61 Boeing 747 aircraft, or just under 4% of the total number of 747s built, first flown commercially in 1970, have been involved in accidents and incidents resulting in a hull loss, meaning that the aircraft was either destroyed or damaged beyond economical repair. Of the 61 Boeing 747 aircraft losses, 32 resulted in no loss of life; in one, a hostage was murdered; and in one, a terrorist died. Some of the aircraft that were declared damaged beyond economical repair were older 747s that sustained relatively minor damage. Had these planes been newer, repairing them might have been economically viable, although with the 747's increasing obsolescence, this is becoming less common. Some 747s have been involved in accidents resulting in the highest death toll of any aviation accident, the highest death toll of any single airplane accident, and the highest death toll of a midair collision. As with most airliner accidents, the root of cause(s) in these incidents involved a confluence of multiple factors that rarely could be ascribed to flaws with the 747's design or its flying characteristics.
China Airlines Flight 605 was a daily non-stop flight departing from Taipei at 6:30 a.m. and arriving at Kai Tak Airport in Hong Kong at 7:00 a.m. local time. On November 4, 1993, the plane went off the runway while landing during a storm. It was the first hull loss of a Boeing 747-400.
UPS Airlines Flight 6 was a cargo flight operated by UPS Airlines. On September 3, 2010, the Boeing 747-400F flying the route between Dubai, United Arab Emirates, and Cologne, Germany, developed an in-flight fire which caused the aircraft to crash, killing both crew members, the only people on board. It was the first fatal air crash for UPS Airlines. The crash prompted a re-evaluation of safety procedures protecting airliners from cockpit smoke.
National Airlines Flight 102 was a cargo flight operated by National Airlines between Camp Bastion in Afghanistan and Al Maktoum Airport in Dubai, with a refueling stop at Bagram Airfield, Afghanistan.
