), resulting in the failure of all four engines. The reason for the failure was not immediately apparent to the crew or ground control. The aircraft was diverted to Jakarta in the hope that enough engines could be restarted to allow it to land there. The aircraft was able to glide far enough to exit the ash cloud, and all engines were restarted (although one failed again soon after), allowing the aircraft to land safely at the Halim Perdanakusuma Airport in Jakarta.

The crew members of the incident segment had boarded the aircraft in Kuala Lumpur, while many of the passengers had been aboard since the flight began in London.

 showing clear skies, the crew switched on engine anti-ice and the passenger seat belt signs as a precaution.

As the flight progressed, smoke began to gather throughout the passenger cabin of the aircraft and it was at first assumed to be cigarette smoke. However, it soon began to grow thicker and had an ominous odour of sulphur. Passengers who had a view out of the aircraft windows noted that the engines were unusually bright with the light shining forward through the fan blades and producing a stroboscopic effect.

At approximately 13:42 UTC (20:42 Jakarta time), engine number four began surging

. The flight crew immediately performed the engine shutdown drill, quickly cutting off fuel supply and arming the fire extinguishers. Less than a minute later, at 13:43 UTC (20:43 Jakarta time), engine two surged and flamed out. Within seconds, and almost simultaneously, engines one and three flamed out prompting the flight engineer to exclaim, "I don't believe it—all four engines have failed!"

Without engine thrust, a 747-200 has a glide ratio of approximately 15:1, meaning it can glide forward 15 kilometres for every kilometre it drops. The flight crew quickly determined that the aircraft was capable of gliding for 23 minutes and covering 91 nautical miles (168.5 km) from its flight level of 37000 feet (11,277.6 m). At 13:44 UTC (20:44 Jakarta time), Greaves declared an emergency to the local air traffic control

, an altitude of at least 11500 feet (3,505.2 m) was required to cross the coast safely. The crew decided that if the aircraft was unable to maintain altitude by the time they reached 12000 feet (3,657.6 m) they would turn back out to sea and attempt to ditch

 into the Indian Ocean. The crew began the engine restart drills, despite being well above the recommended maximum engine in-flight start envelope altitude of 28000 feet (8,534.4 m). The attempts failed.

Despite the lack of time, Moody made an announcement to the passengers that has been described as "a masterpiece of understatement

":
As pressure within the cabin fell, oxygen masks dropped from the ceiling—an automatic emergency measure to make up for the lack of air. On the flight deck however, Greaves's mask was broken; the delivery tube had detached from the rest of the mask. Moody swiftly decided to descend at 1,800 m per minute to an altitude where there was enough pressure in the outside atmosphere to breathe almost normally.

At 13500 feet (4,114.8 m), they were approaching the altitude at which they would have to turn over the ocean and attempt a risky ditching. Although there were guidelines for the procedure, no one had ever tried it in a Boeing 747, nor has anyone since. As they performed the engine-restart procedure, engine number four started, and at 13:56 UTC (20:56 Jakarta time), Moody used its power to reduce the rate of descent. Shortly thereafter, engine three restarted, allowing him to climb slowly. Shortly after that, engines one and two successfully restarted as well. The crew subsequently requested and expedited an increase in altitude to 11500 feet (3,505.2 m) in order to clear the high mountains of Indonesia.

As the aircraft approached its target altitude, the St Elmo's fire effect on the windscreen returned. Moody throttled back; however, engine number two surged again and had to be shut down. The crew immediately descended and held 12000 feet (3,657.6 m).

As Flight 9 approached Jakarta, the crew found it difficult to see anything through the windscreen, and had to make the approach almost entirely on instruments, despite reports of good visibility. The crew decided to fly the ILS, Instrument Landing System

). He then called out how high they should be at each DME step along the final approach to the runway, creating a virtual glide slope for them to follow. It was, in Moody's words, "a bit like negotiating one's way up a badger

's arse." Although the runway lights could be made out through a small strip of the windscreen, the landing lights on the aircraft seemed to be inoperable. After landing, the flight crew found it impossible to taxi, due to glare from apron floodlights which made the already sandblasted windscreen opaque.

Aftermath

It was found that City of Edinburghs problems had been caused by flying through a cloud of volcanic ash

. Because the ash cloud was dry, it did not show up on the weather radar, which is designed to detect the moisture in clouds. The cloud sandblasted the windscreen and landing light covers and clogged the engines. As the ash entered the engines, it melted in the combustion chambers and adhered to the inside of the power-plant. As the engine cooled from not running and as the aircraft descended out of the ash cloud, the molten ash solidified and enough broke off to allow air to flow smoothly through the engine allowing a successful restart. The engines had enough electrical power to restart because one generator and the onboard batteries were still operating; electrical power is required for ignition of the engines.

Engines one, two and three were replaced at Jakarta, as well as the windscreen, and the fuel tanks were cleared of the ash that had entered them through the pressurisation ducts, contaminating the fuel and requiring that it be disposed of. After being ferried back to London, engine number four was replaced and major work was undertaken to return the aircraft to service. G-BDXH also entered the Guinness Book of Records

. Following the incident, the crew and passengers formed the Galunggung Gliding Club as a means to keep in contact.

One of the passengers, Betty Tootell, wrote a book about the incident, All Four Engines Have Failed. She managed to trace some 200 of the 247 passengers on the flight, and went on to marry a fellow survivor, James Ferguson, who had been seated in the row in front of her. She notes: "The 28th December 2006 marks the start of our 14th year of honeymoon, and on the 24th June 2007 many passengers and crew will no doubt gather to celebrate the 25th anniversary of our mid-air adventure."
