when and where did british airlines have all 4 engines fail due to ingesting volvanic ash?

1982, Indonesia\n"After the Galunggung, Indonesia volcanic event in 1982, a British Airways Boeing 747 flew through an ash cloud that fouled all 4 engines, stopping them. The plane descended from 36,000 feet to only 12,000 feet before the crew could manage to restart the engines."

Where there any geological hints previous?\nHow was the emergency action plan enacted?\nWhat was the survival rate in the ash zone?

Pardon my stupidity in Engineering...but there is magnesium in engines?? Huh...I learned something new I guess....

The last major eruption on Galunggung was in 1982, which had a Volcanic Explosivity Index of 4 and killed 35 people. This eruption also brought the dangers of volcanic ash to aviation to worldwide attention, after two Boeing 747 passenger jets flying downwind of the eruption suffered temporary engine failures and damage to exterior surfaces, both planes being forced to make emergency landings at Jakarta.\n\nOne, a British Airways aircraft carrying 240 passengers, accidentally entered the ash cloud during night time in June 1982 150 km downwind of the volcano. All four engines failed and the aircraft descended for 16 minutes, losing 7500 metres of its 11500 metre altitude, until the crew managed to restart the engines (See main article British Airways Flight 9).\n\nThe following month a Singapore Airlines aeroplane with 230 passengers aboard also inadvertently entered the cloud at night time, and three of its four engines stopped. The crew succeeded in restarting one of the engines after descending 2400 metres. Both aircraft suffered serious damage to their engines and exterior surfaces[1].\n\nA hummocky deposit known as the Ten Thousand Hills of Tasikmalaya attracted the attention of early 20th century geologists. Houses were built on the hummocks since they provided good defence against hostile people, and being above the paddy fields were free of mosquitoes and rats.\n\nOriginally, it was thought that either it had been formed by a lahar caused by the release of the waters of the crater lake, or that it was man-made; composed of rocks and boulders dumped there after being cleared from paddy fields.\n\nHowever, in the light of the Mount St. Helens eruption of 1980 and from examination of the Mount Shasta deposits it has become clear that the hummocks are a debris-avalanche deposit. Like these mountains, Galunggung has a horseshoe-shaped crater indicating a massive landslide, and examination of shattered lava blocks revealed them to be similar to deposits on the other two volcanoes. According to radiocarbon dating of samples taken from a lava flow the landslide happened within the last 23,000 years.\n\nYou could get more information from the link below...

lead, poisonous gas emmissions...you are talking about damage...this stuff can kill you

Methane gas from the ocean floor..in large amounts..it can cause a tanker size ship to sink in less than 10 seconds..it can cause..plane instruments to read you are climbing in altitude when they are not....1% methane gas in the air is enough to cause a plane engine to stop running instantly.. thus planes crashing ...it has been looked into very well ..I agree..with that theory.

It was the De Havilland Aircraft Company.\n\nThat's all I know, I'm afraid.

The only environmental concerns that come to mind are emissions and fuel.\n\nThere are no catalytic converters on aircraft, so any unburnt hydrocarbons or NOx/SOx/COx would be released into the air.\n\nOn the fuel side, most piston aircraft use leaded fuels, so when fuel is spilled or leaks, lead is entering the ground.  The large majority of fuel used in aviation is jet fuel, which is pretty close to diesel or kerosene and so no more harmful than those two.  Ultimately, no aircraft owner is deliberately dumping their leaded fuel, because it's damned expensive. :P

No Smoke!  They are called contrails(condensation trails)\n\nContrails are created in one of two ways:\n\n1. First, the airplane's exhaust increases the amount of moisture in the air, which can push the water content of the air past saturation point. This causes condensation to occur, and the contrail to form.\n\nAviation fuel such as petrol/gasoline (piston engines) or paraffin/kerosene (jet engines) consists primarily of hydrocarbons. When the fuel is burned, the carbon combines with oxygen to form carbon dioxide; the hydrogen also combines with oxygen to form water, which emerges as steam in the exhaust. For every gallon of fuel burned, approximately one gallon of water is produced, in addition to the water already present as humidity in the air used to burn the fuel. At high altitudes this steam emerges into a cold environment, (as altitude increases, the atmospheric temperature drops) which lowers the temperature of the steam until it condenses into tiny water droplets and/or desublimates into ice. These millions of tiny water droplets and/or ice crystals form the contrails. The temperature drop (and therefore, time and distance) the steam needs to condense accounts for the contrail forming some way behind the aircraft's engines.\n\n2. The wings of an airplane cause a drop in air pressure in the vicinity of the wing (this is partly what allows a plane to fly). This drop in air pressure brings with it a drop in temperature, which can cause water to condense out of the air and form a contrail.\n\nExhaust contrails tend to be more stable and long-lasting than wing-tip contrails, which are often disrupted by the aircraft's wake and are commonly very short-lived.

wow...in 1968 i watched what appeared to be a shiny metallic piece of  crumpled metal tumble towards earth for 10 minutes, it was probably space debris or toilet ejecta from a passing airliner.what you seen was likely hardboard insulation like they use on construction sites, that stuff will fly a long ways with little wind....or else it was a runaway magic carpet

I was not aware that they asked to close them.  I have never heard that before.  What airline were you on?
