As of July 2020, the 777 has been involved in 29 aviation accidents and incidents, including a total of eight hull losses (five in-flight and three on-ground incidents), resulting in 541 fatalities along with three hijackings.
The first fatality involving the twinjet occurred in a fire while an aircraft was being refueled at Denver International Airport in the United States on September 5, 2001, during which a ground worker sustained fatal burns.
The aircraft, operated by British Airways, suffered fire damage to the lower wing panels and engine housing; it was later repaired and returned to service.

The first hull loss occurred on January 17, 2008, when a 777-200ER with Rolls-Royce Trent 895 engines, flying from Beijing to London as British Airways Flight 38, crash-landed approximately 1,000 feet (300 m) short of Heathrow Airport's runway 27L and slid onto the runway's threshold.
There were 47 injuries and no fatalities.
The impact severely damaged the landing gear, wing roots and engines.
The accident was attributed to ice crystals suspended in the aircraft's fuel clogging the fuel-oil heat exchanger (FOHE).
Two other minor momentary losses of thrust with Trent 895 engines occurred later in 2008.
Investigators found these were also caused by ice in the fuel clogging the FOHE.
As a result, the heat exchanger was redesigned.

The second hull loss occurred on July 29, 2011 when a 777-200ER scheduled to operate as EgyptAir Flight 667 suffered a cockpit fire while parked at the gate at Cairo International Airport before its departure.
The aircraft was evacuated with no injuries, and airport fire teams extinguished the fire.
The aircraft sustained structural-, heat- and smoke damage, and was written off.
Investigators focused on a possible short circuit between an electrical cable and a supply hose in the cockpit crew oxygen system.

The third hull loss occurred on July 6, 2013 when a 777-200ER, operating as Asiana Airlines Flight 214, crashed while landing at San Francisco International Airport after touching down short of the runway.
The 307 surviving passengers and crew on board evacuated before fire destroyed the aircraft.
Two passengers, who had not been wearing their seatbelts, were ejected from the aircraft during the crash and were killed.
A third passenger died six days later as a result of injuries sustained during the crash.
These were the first fatalities in a crash involving a 777 since its entry into service in 1995.
The official accident investigation concluded in June 2014 that the pilots committed 20 to 30 minor to significant errors in their final approach, and that complexities of the automated controls contributed to the accident.

The probable fourth hull loss occurred on March 8, 2014 when a 777-200ER carrying 227 passengers and 12 crew, en route from Kuala Lumpur to Beijing as Malaysia Airlines Flight 370, was reported missing.
Air Traffic Control's last reported coordinates for the aircraft were over the South China Sea at 6°55′15″N 103°34′43″E. After the search for the aircraft began, Malaysia's prime minister announced on March 24, 2014 that after analysis of new satellite data it was now to be assumed "beyond reasonable doubt" that the aircraft had crashed in the Indian Ocean and there were no survivors.
The cause remains unknown, but the Malaysian Government in January 2015, declared it an accident.
US officials believe the most likely explanation to be that someone in the cockpit of Flight 370 re-programmed the aircraft's autopilot to travel south across the Indian Ocean.
On July 29, 2015, an item later identified as a flaperon strongly suspected to be from the missing aircraft was found on the island of Réunion in the western Indian Ocean.

The fourth confirmed hull loss occurred on July 17, 2014, when a 777-200ER, bound for Kuala Lumpur from Amsterdam as Malaysia Airlines Flight 17 (MH17), broke up in mid-air and crashed in the Donetsk province in eastern Ukraine, after being hit by an anti-aircraft missile.
All 298 people (283 passengers and 15 crew) on board were killed, making this the deadliest
