Aircraft, crew, and passengers


Aircraft

Flight 990 was being flown in a Boeing 767-366ER aircraft with registration named ''

'' after a pharaoh from the 18th Dynasty. The aircraft, a stretched, extended-range version of the standard 767, was the 282nd 767 built. It was delivered to

as a new aircraft on September 26, 1989.


Cockpit crew

Flight 990's cockpit crew consisted of 57-year-old Captain Ahmed El-Habashi, 36-year-old First Officer Adel Anwar, who was switching duty with another co-pilot so he could return home in time for his wedding, 52-year-old relief Captain Raouf Noureldin, 59-year-old relief First Officer Gameel Al-Batouti, and the airline's chief pilot for the Boeing 767, Captain Hatem Rushdy. Captain El-Habashi was a veteran pilot who had been with EgyptAir for 36 years and had accumulated about 14,400 total flight hours, more than 6,300 of which were on the 767. Relief First Officer Al-Batouti had close to 5,200 flight hours in the 767 and a total of roughly 12,500 hours. Because of the 10-hour scheduled flight time, the flight required two complete flight crews, each consisting of one
captain Captain is a title, an appellative for the commanding officer of a military unit; the supreme leader of a navy ship, merchant ship, aeroplane, spacecraft, or other vessel; or the commander of a port, fire or police department, election precinct, e ...
and one first officer. EgyptAir designated one crew as the "active crew" and the other as the "cruise crew", sometimes also referred to as the " relief crew". While no formal procedure specified when each crew flew the aircraft, the active crew customarily made the takeoff and flew the first four to five hours of the flight. The cruise crew then assumed control of the aircraft until about one to two hours before landing, when the active crew returned to the cockpit and assumed control of the aircraft. EgyptAir designated the captain of the active crew as the
pilot-in-command The pilot in command (PIC) of an aircraft is the person aboard the aircraft who is ultimately responsible for its operation and safety during flight. This would be the captain in a typical two- or three- pilot aircrew, or "pilot" if there is onl ...
or the commander of the flight. While the cruise crew was intended to take over far into the flight, relief first officer Al-Batouti entered the cockpit and recommended that he relieve the command first officer 20 minutes after takeoff. Command first officer Anwar initially protested, but eventually relented.


Passengers

The flight was carrying 203 passengers from eight countries:

; the rest boarded in New York. Four were nonrevenue EgyptAir crew members. Included in the passenger manifest were 33 Egyptian military officers returning from a training exercise; among them were two brigadier generals, a colonel, a major, and four other air force officers. After the crash, newspapers in Cairo were prevented by censors from reporting the officers' presence on the flight. The authorities at John F. Kennedy International Airport (JFK) used the JFK Ramada Plaza to house relatives and friends of the victims of the crash. Due to its similar role after several aircraft crashes, the Ramada became known as the "Heartbreak Hotel".


Flight details

At 1:20 am EST (06:20 UTC), the aircraft took off from JFK's runway 22R. At 1:44, the flight reached its cruising altitude of 33,000 feet. At 1:48, captain El-Habashi left the cockpit and went to the lavatory. During that time, relief first officer Al-Batouti was alone in the cockpit. At 1:48:39, he began to exclaim, "I rely on God," and, at 1:49:45, disengaged the autopilot. The autopilot-disengagement warning was not heard on the CVR, indicating that the autopilot was disengaged manually, and, for the next 10 seconds, the aircraft remained in straight and level flight.


First dive and recovery

At 1:49:53, the throttles of both engines were moved to idle, and, 1 second later, the aircraft entered an increasingly-steep dive, resulting in
weightlessness Weightlessness is the complete or near-complete absence of the sensation of weight. It is also termed zero gravity, zero G-force, or zero-G. Weight is a measurement of the force on an object at rest in a relatively strong gravitational fie ...
(zero-g) throughout the cabin. Despite this, the captain was able to fight the lack of gravity and re-enter the cockpit. The speed of the 767 was now dangerously close to the sound barrier, exceeding its design limits and beginning to weaken its airframe. At 1:50:19, the flight reached its maximum rate of descent, per minute. Between 1:50:21 and 1:50:23, as the captain began to pull back on his control column while relief first officer Al-Batouti moved both engines' start levers from the "run" to the "cutoff" position, shutting off fuel flow to the engines. Immediately afterwards, the captain pushed both throttles to their maximum position, but this had no effect, due to the engines' fuel supply having been cut off. The captain then deployed the speedbrakes, which slowed the aircraft's dive, bringing it back to a safer speed. Without fuel, both engines then ran down to a stop, causing the aircraft to lose all electrical power, including to both

; the last secondary radar return from the flight was received at 1:50:34, the FDR stopped recording at 1:50:36, and the CVR stopped recording at 1:50:38, approximately when the aircraft pulled out from the first dive.


Climb, second dive, and crash

Due to the loss of electrical power, the flight recorders stopped recording by 1:50:38; thus, all that is known from this point on is based on primary radar returns from the aircraft (produced by the reflection of radar waves from its surface) and on the distribution of its wreckage. Radar data indicated that, at approximately 1:50:38, the aircraft entered a steep climb, presumably due to the abrupt maneuvers made by the flightcrew to recover from the dive. Between 1:50:38 and 1:51:15, the 767 climbed from feet back to , during which time its heading changed from 80° to 140°. At 1:51:15, the aircraft entered another steep dive, with an average descent rate of around per minute. At some point during the final descent, the left engine and some other small pieces of debris separated from the aircraft due to the extreme structural stresses produced during the dive. The stress placed on the airframe caused structural integrity to fail at approximately 10,000 feet. The aircraft sections impacted the ocean at approximately 1:52 am EST, with the last primary radar return from the aircraft being received at 1:52:05. All 217 people on board were killed.


Air traffic control

lers provided transatlantic flight-control operations as a part of the New York Air Route Traffic Control Center (referred to in radio conversations simply as "Center" and abbreviated in the reports as "ZNY"). The airspace is divided into "areas", and "Area F" was the section that oversaw the airspace through which Flight 990 was flying. Transatlantic commercial air traffic travels via a system of routes called the
North Atlantic Tracks North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), is a structured set of transatlantic flight routes that stretch from the eastern North America to western Europe across the Atlantic Ocean, within the ...
, and Flight 990 was the only aircraft at the time assigned to fly North Atlantic Track Zulu. Also, a number of military operations areas are over the Atlantic, called "warning areas", which are also monitored by New York Center, but records show that these were inactive the night of the accident. Interaction between ZNY and Flight 990 was completely routine. After takeoff, Flight 990 was handled by three different controllers as it climbed up in stages to its assigned cruising altitude. The aircraft, like all commercial airliners, was equipped with a Mode C transponder, which automatically reported the plane's altitude when queried by the ATC radar. At 01:44, the transponder indicated that Flight 990 had leveled off at FL330. Three minutes later, the controller requested that Flight 990 switch communications radio frequencies for better reception. A pilot on Flight 990 acknowledged on the new frequency. This was the last transmission received from the flight. The records of the radar returns then indicate a sharp descent, with the plane dropping in 36 seconds before its last altitude report at 06:50:29

(UTC; 01:50:29 Eastern Standard Time). Several subsequent "primary" returns (simple radar reflections without the encoded Mode C altitude information) were received by ATC, the last being at 06:52:05. At 06:54, the ATC controller tried notifying Flight 990 that radar contact had been lost, but received no reply. Two minutes later, the controller contacted

(CVR) recorded the captain excusing himself to go to the lavatory, followed 30 seconds later by the first officer saying in Egyptian Arabic "''Tawkalt ala Allah''," which can be translated as "I put my trust in God." A minute later, the autopilot was disengaged, immediately followed by the first officer again repeating the same Arabic phrase which can be also translated as, "I rely on God." Three seconds later, the throttles for both engines were reduced to idle, and both elevators were moved 3° nose down. The first officer repeated "I rely on God" seven more times before the captain suddenly asked repeatedly, "What's happening, what's happening?" The flight data recorder (FDR) reflected that the elevators then moved into a split condition, with the left elevator up and the right elevator down, a condition that is expected to result when the two control columns are subjected to at least of opposing force. At this point, both engines were shut down by moving the start levers from run to cutoff. The captain asked, "What is this? What is this? Did you shut the engines?" The captain is then recorded as saying, "get away in the engines" (this is the literal translation that appears in the NTSB transcript), followed by "shut the engines". The first officer replies "It's shut". The final recorded words are the captain repeatedly stating, "Pull with me" but the FDR data indicated that the elevator surfaces remained in a split condition (with the left surface commanding nose up and the right surface commanding nose down) until the FDR and CVR stopped recording. No other aircraft were in the area, and no indication was given that an explosion occurred on board. The engines operated normally for the entire flight until they were shut down. From the presence of a western debris field about from the eastern debris field, the NTSB concluded that the left engine and some small pieces of wreckage separated from the aircraft before water impact.


Search-and-rescue operations

The aircraft crashed in international waters, so the Egyptian government had the right to initiate its own

Defection of Hamdi Hanafi Taha

In February 2000, EgyptAir 767 captain Hamdi Hanafi Taha sought political asylum in London after landing his aircraft there. In his statement to British authorities, he claimed to have knowledge of the circumstances behind the crash of Flight 990. Taha attested that first officer Gameel Al-Batouti had intentionally crashed the plane to exact revenge on an airline executive, who had recently demoted Al-Batouti, and happened to be onboard. Taha also is reported to have said that he wanted to "stop all lies about the disaster," and to put much of the blame on EgyptAir management.

, said, "This pilot can't know anything about the plane; the chances that he has any information bout the crash of Flight 990are very slim." EgyptAir officials also immediately dismissed Taha's claim. American investigators confirmed key aspects of Taha's information, but decided not to anger the Egyptian government further by issuing any official statement about Al-Batouti's motive. EgyptAir terminated Taha's employment, and his application for British asylum was reportedly declined, though he gave an extensive 2002 newspaper interview in London, and a 2005 documentary credited him as "Exiled Captain".


NTSB investigation and conclusion

The NTSB investigation centered on the actions of the relief first officer, Gameel Al-Batouti. The NTSB determined that the only way for the observed split elevator condition to occur was if the left seat pilot (the captain's position) was commanding nose up while the right seat pilot (the first officer's position) commanded nose down. As the Egyptian investigation forwarded various mechanical failure scenarios, they were each tested by the NTSB and found not to match the factual evidence. The NTSB concluded that no mechanical failure scenario either they or the Egyptian investigation could come up with matched the evidence on the ground, and that even if mechanical failure was a factor, the 767's design would have made the situation recoverable. The NTSB's final report was issued on March 21, 2002, after a two-year investigation, and concluded as "not determined". From the NTSB report's "Summary" section:
1. The accident airplane's nose-down movements did not result from a failure in the elevator control system or any other airplane failure. 2. The accident airplane's movements during the initial part of the accident sequence were the result of the relief first officer's manipulation of the controls. 3. The accident airplane's movements after the command captain returned to the cockpit were the result of both pilots' inputs, including opposing elevator inputs where the relief first officer continued to command nose-down and the captain commanded nose-up elevator movements.
From the NTSB report's "Probable Cause" section:
The National Transportation Safety Board determines that the probable cause of the EgyptAir flight 990 accident is the airplane's departure from normal cruise flight and subsequent impact with the Atlantic Ocean as a result of the relief first officer's flight control inputs. The reason for the relief first officer's actions was not determined.


ECAA investigation and conclusion

After formally ceding responsibility for the investigation of the accident to the NTSB, the Egyptian authorities became increasingly unhappy with the direction the investigation was heading, and launched their own investigation in the weeks following the accident. The ECAA report concluded that "the Relief First Officer did not deliberately dive the airplane into the ocean" and that mechanical failure was "a plausible and likely cause of the accident". William Langewiesche, an aviation journalist, said: " the case of the Egyptians, they were following a completely different line of thinking. It seemed to me that they knew very well that their man, Batouti, had done this. They were pursuing a political agenda that was driven by the need to answer to their higher-ups in a very pyramidal, autocratic political structure. The word had been passed down from on high, probably from Mubarak himself, that there was no way that Batouti, the co-pilot, could have done this. For the accident investigators in Egypt, the game then became not pursuing the truth, but backing the official line."


Responses to reports

The NTSB investigation and its results drew criticism from the Egyptian government, which advanced several alternative theories about mechanical malfunction of the aircraft. The theories proposed by Egyptian authorities were tested by the NTSB, but none was found to match the facts. For example, an elevator assembly hardover (in which the elevator in a fully extended position sticks because the hinge catches on the tail frame) proposed by the Egyptians was discounted because the flight recorder data showed the elevator was in a "split condition". In this state, one side of the elevator is up and the other down; on the 767, this condition is only possible through flight control input (i.e., one yoke is pushed forward, the other pulled backward). Some evidence indicated that one of the right elevator's power control units may have suffered a malfunction, and the Egyptian investigation mentioned this as a likely cause of the crash. While noting that the damage did indeed exist, the NTSB countered that it was more likely a result of the crash rather than a pre-existing problem, as the 767 is designed to remain airworthy even with two PCUs failed.


Media coverage

While the official investigation was proceeding, speculation about the crash ran rampant in both Western and Egyptian media.


Western media speculation

Long before the NTSB issued its final report, Western media began to speculate about the meaning of the recorded cockpit conversations and about possible motives – including suicide and terrorism – behind Al-Batouti's actions on the flight. The speculation, in part, was based on leaks from an unnamed federal law-enforcement official that the crew member in the co-pilot's seat was recorded as saying, "I made my decision now. I put my faith in God's hands." During a press conference held on November 19, 1999, NTSB chairman Jim Hall denounced such speculation, and said that it had "done a disservice to the long-standing friendship between the people of the United States of America and Egypt." On November 20, 1999, the Associated Press quoted senior American officials as saying that the quotation was not in fact on the recording. It is believed that the speculation arose from a mistranslation of an Egyptian Arabic phrase (''Tawkalt ala Allah'') meaning "I rely on God." London's ''

'', quoting unnamed sources, speculated that the relief first officer had been "traumatised by war," and was depressed because many members of his fighter squadron in the 1973 war had been killed. The unprecedented presence of 33 members of the Egyptian general staff on the flight (contrary to standard operating procedure) fed a number of conspiracy theories. Some opined that it was an action (and potentially a conspiracy) of Muslim extremists against Egypt. Others countered that

had targeted them.


Egyptian media reaction and speculation

The Egyptian media reacted with outrage to the speculations in the Western press. The state-owned '' Al Ahram Al Misri'' called Al-Batouti a "martyr", and the Islamist '' Al Shaab'' covered the story under a headline that stated, "America's goal is to hide the truth by blaming the EgyptAir pilot." At least two Egyptian newspapers, ''

crews stayed at the same hotel in New York). ''Al Shaab'' also accused US officials of secretly recovering the FDR, reprogramming it, and throwing it back into the water to be publicly recovered. Unifying all the Egyptian press was a stridently held belief that "it is inconceivable that a pilot would kill himself by crashing a jet with 217 people aboard. 'It is not possible that anyone who would commit suicide would also kill so many innocent people alongside him,' said Ehab William, a surgeon at Cairo's Anglo-American Hospital." The Egyptian media also reacted against Western speculation of terrorist connections. The ''Cairo Times'' reported, "The deceased pilot's nephew has lashed out in particular against speculation that his uncle could have been a religious extremist. 'He loved the United States,' the nephew said. 'If you wanted to go shopping in New York, he was the man to speak to, because he knew all the stores.'"


Reaction of the Egyptian public

William Langewiesche, an author, journalist, and aviator, said that in Cairo, he encountered three groups of people. He said that the ordinary Cairenes believed that an American conspiracy existed to attack EgyptAir 990 and that the Americans were covering up the fact. He added that a small group of Cairenes, mostly consisting of "

", "knew perfectly well that Batouti, the co-pilot, had pushed that airplane into the water, and that the Egyptian government was stonewalling and was engaged in what they saw as a typical exercise in Egyptian governing." Langewiesche said that "people involved directly in the investigation" had "presented a uniform party line, a uniform face with very few cracks. They stonewalled me, and that in itself was very interesting." Langewiesche argued that "in the stonewalling, they were revealing themselves" and that if they truly believed Batouti were innocent, they would have invited Langewiesche to see proof of this theory.


Aftermath

After the crash, at November 14, 1999, the airline changed the flight number for the JFK to Cairo route from MS990 to MS986, with the outbound changing from MS989 to MS985, and discontinued the service to Los Angeles. Flight 986 is operated using a

about the flight that was broadcast in March 2000. The documentary looked at the preliminary NTSB conclusion and speculations surrounding it. In the documentary, the NTSB data were used with a flight simulator of the same aircraft model to try to reconstruct the circumstances of the crash, but the simulator failed three times to replicate the NTSB theory for plunging a fully functioning 767 from 33,000 ft (10,000 m) to 19,000 ft (5,800 m) in 37 seconds.

'' (called ''Air Emergency'' and ''Air Disasters'' in the U.S. and ''Air Crash Investigation'' in the UK and elsewhere around the world). The episode was broadcast with the title "EgyptAir 990" in the United Kingdom, Australia, and Asia. In response to the ECAA's claim of NTSB unprofessionalism, former NTSB director of aviation safety Bernard Loeb stated: The ''Mayday'' dramatization of the crash was based on ATC tapes, as well as the CVR recordings. In interviews conducted for the program, the relief first officer's family members vehemently disputed the suicide and deliberate crash theories, and dismissed them as biased. The program nevertheless concluded that Al-Batouti crashed the plane for personal reasons; he had been severely reprimanded by his supervisor for sexual harassment after allegedly "exposing himself to teenaged girls and propositioning hotel guests", and the supervisor was, in fact, on board the plane when it was brought down. This dramatization also depicts the relief first officer forcing the plane down while the command captain attempts to pull the plane up. Despite this, upon conclusion, the program stresses the official NTSB conclusion and the fact it makes no mention of a suicide mission. Rather, it simply states that the crash was a direct result of actions made by the co-pilot for reasons "not determined".
