Iran C-130 Plane Crash(2009)

A military transport plane has crashed on the outskirts of the Iranian capital Tehran, killing at least 128 people.

The plane was attempting an emergency landing at Mehrabad airport and came down in a residential district, hitting a 10-storey apartment building.

The impact set off a big explosion, setting fire to the building.

Iranian state-run radio said all 94 passengers and crew on board the C-130 plane, and 34 people on the ground, were killed.

The aircraft had just taken off when the pilot reported an emergency and turned back, before losing control of the aircraft.

"I saw the aeroplane. There was smoke coming out of one engine. It went into the ground very fast, very close to the building," said 30-year-old Mohammad Rasooli, a local resident.

"There was a huge explosion which engulfed the housing block."

Most of the passengers on board the plane were journalists and photographers from Iranian news agencies on their way to cover military manoeuvres on the southern coast. Nearly 40 employees of state-run television died.

The building remained standing but is a scorched shell.

Officials said several children, at home because schools were closed because of a smog alert in the capital, were among those who died in the apartment block.

"Most of the victims on the ground are women and children who were at home," Lieutenant Nasser Sedigh-Nia, who witnessed the crash, told AFP news agency.

An interior ministry spokesman said some of those killed on the ground had been in their cars, whose burnt-out shells littered the crash site.

Scores of people were taken to hospitals suffering from burns and the effects of smoke.

Scuffles broke out as police cordoned off the crash site, trying to keep hundreds of anxious residents from pushing past them.

And journalists at the site were beaten and had their tapes confiscated by the security forces.

The BBC's Frances Harrison in Tehran says the Iranian army has denied rumours that the flight crew was aware there were technical problems with the plane.

It was said to have nearly crashed a week ago, and its engines had to be switched on and off five times before it could take off on its final flight.

In a message carried by state media, Iranian President Mahmoud Ahmadinejad said: "I learned of the catastrophe and the fact that members of the press have been martyred.

"I offer my condolences to the supreme leader and to the families of the victims".

The Iranian air force is believed to have about 15 ageing US-made C-130s in operation, dating back to before the 1979 Islamic revolution and the US boycott of Iran.

The country's civil and military aircraft have a poor safety record.

In 2003, an Iranian Ilyushin-76 troop carrier crashed in south-east Iran killing all 276 Revolutionary Guard soldiers and crew aboard.

Officials blame the high frequency of crashes on a lack of aviation spare parts due to US sanctions.

Mehrabad is the oldest airport in Tehran and handles both domestic and military flights.

When it was built more than 60 years ago it was located outside the capital, but with the growth of Tehran's urban sprawl the airport has become surrounded by residential areas.

Adam Air 574(2007)

Adam Air Flight 574 (KI-574) was a scheduled domestic passenger flight operated by Adam Air between the Indonesian cities of Surabaya (SUB) and Manado (MDC) which disappeared near Polewali in Sulawesi on 1 January 2007. The plane, a Boeing 737-4Q8, was ultimately determined to have crashed into the ocean, from which some smaller pieces of wreckage have been recovered. The flight recorders ("black boxes") were retrieved from the ocean on 28 August 2007, while salvage efforts for some larger pieces of wreckage continued. All 102 people on board are missing and presumed dead.

A full national investigation was immediately launched into the disaster, uncovering multiple maintenance issues concerning the airline as a whole, including a large number concerning the aircraft. Another possibility proposed by the families of some of the deceased is that the crash was due to a faulty rudder valve, known to have caused previous accidents and incidents on Boeing 737s. Debris location has indicated that the plane likely struck the ocean intact. The final report, released on 25 March 2008, concluded that the pilots lost control of the aircraft after they became preoccupied with troubleshooting the inertial reference system and inadvertently disconnected the autopilot.

The crash is one of several transportation accidents, including the subsequent non-fatal crash of Adam Air Flight 172, which between them have resulted in large-scale transport safety reforms in Indonesia, as well as the United States downgrading its safety rating of Indonesian aviation, and of the entire Indonesian fleet being added to the list of air carriers banned in the EU.

BOAC Flight 781(1954)

On 10 January 1954, BOAC Flight 781 a de Havilland Comet 1 (type DH-106), took off from Ciampino Airport in Rome, Italy en route to Heathrow Airport in London, England on the final leg of its flight from Singapore. At about 10:00 GMT, the aircraft suffered an explosive decompression at altitude and crashed into the Mediterranean Sea, killing everyone on board.

The flight was operated by British Overseas Airways Corporation (BOAC) using the aircraft G-ALYP.

Investigators at the RAE were able to conclude that the crash had been due to failure of the pressure cabin at the forward ADF window in the roof. This 'window' was in fact one of two apertures for the aerials of an electronic navigation system in which opaque fibreglass panels took the place of the window 'glass.' The failure was a result of metal fatigue caused by the repeated pressurisation and de-pressurisation of the aircraft cabin. Another fact was that the supports around the windows were riveted, not glued, as the original specifications for the aircraft had called for. The problem was exacerbated by the punch rivet construction technique employed. Unlike drill riveting, the imperfect nature of the hole created by punch riveting caused manufacturing defect cracks which may have caused the start of fatigue cracks around the rivet. The investigators examined the final piece of wreckage with a regular microscope.
