| The silver shell of the 747, balanced on three piles of wooden pallets, shudders and wobbles alarmingly as its left wing slaps the ground like a wounded bird. | The silver shell of the 747, balanced on three piles of wooden pallets, shudders and wobbles alarmingly as its left wing slaps the ground like a wounded bird. |

| After decades of safely transporting thousands of people to destinations around the globe, this is the fate that awaits aircraft when they are too old, or their owners can't afford them any more. They come to an airfield in Gloucestershire to be scrapped. | After decades of safely transporting thousands of people to destinations around the globe, this is the fate that awaits aircraft when they are too old, or their owners can't afford them any more.

| Plane parts are bought for any number of reasons. Anything from flying controls to doors and windows are bought by aviation companies for reuse, snapped up by production companies for film and TV and by the likes of the SAS for training. Seats are even bought by enthusiasts for their homes. | Plane parts are bought for any number of reasons.

| Air Salvage International (ASI), based at Cotswold Airport in Kemble, is the largest specialist breaker in Britain and claims to be the busiest. Mark Gregory started ASI 15 years ago, after working as a mechanic for an aviation firm. Since then it has handled 350 aircraft. | Air Salvage International (ASI), based at Cotswold Airport in Kemble, is the largest specialist breaker in Britain and claims to be the busiest.

| The company, which employs 25 staff, has been one of the few beneficiaries of the economic downturn. Last year it handled more planes than ever due to airlines going bankrupt or suffering huge losses. It dismantled 30 planes, usually it's more like 15 to 25. There are currently nine planes at the airfield waiting to be scrapped. | The company, which employs 25 staff, has been one of the few beneficiaries of the economic downturn.

| It costs a plane's owner between £60,000 to £120,000 to dismantle a 747, depending on what is required. The entire process can take up to 12 weeks. Up to 50% of an older jumbo jet can be recycled and on average they are taken out of service after 24 years. This can be for a number of reasons - wear and tear, costing too much to repair or maintain or simply being too old fashioned. | It costs a plane's owner between £60,000 to £120,000 to dismantle a 747, depending on what is required.

| The process can be categorised into three areas: engines, component parts and fuselage. This is how it's done. | The process can be categorised into three areas: engines, component parts and fuselage. This is how it's done. |

| The core value of a plane is its engine, which can make up 80% of its total value. The rest of the plane can be sold for spares for about £234,000 ($350,000). | The core value of a plane is its engine, which can make up 80% of its total value.

| The engines are the first thing to come off a plane after it arrives. They are tested and then can be fitted to another plane, stripped down further for parts or returned to the manufacturers to be repaired. You get more money for parts, rather than reselling the engine as whole, says Mr Gregory. | The engines are the first thing to come off a plane after it arrives.

| The parts of a plane that can be taken off for reuse include items such as flight deck instruments, black box flight recorders, air conditioning, flying controls, landing gears (wheels and hydraulics), flaps and spoilers, fuel system and cabin interiors - like doors and windows. | The parts of a plane that can be taken off for reuse include items such as flight deck instruments, black box flight recorders, air conditioning, flying controls, landing gears (wheels and hydraulics), flaps and spoilers, fuel system and cabin interiors - like doors and windows. |

| Parts must undergo stringent checks and be given a Certificate of Airworthiness before they can be reused on working aircraft. This can be done on-site by ASI or parts are returned to the original manufacturer by their owner for a complete overhaul. | Parts must undergo stringent checks and be given a Certificate of Airworthiness before they can be reused on working aircraft.

| Every part, right down to the nuts and bolts, has accompanying paperwork that details everything about its history. These documents are kept for nine years after a plane is destroyed. | Every part, right down to the nuts and bolts, has accompanying paperwork that details everything about its history.

| Up to 50% of an older 747 can be recycled, whereas a newer Airbus A320 can have 95% of its parts reused. What can't be recycled is sent to a landfill site. | Up to 50% of an older 747 can be recycled, whereas a newer Airbus A320 can have 95% of its parts reused.

| Apart from scrapping the metal, or saving parts for reuse on existing aircraft, what else can you do with an old plane? Plenty, according to Mr Gregory. | Apart from scrapping the metal, or saving parts for reuse on existing aircraft, what else can you do with an old plane? Plenty, according to Mr Gregory. |
| A television production company has blown up a plane to film a demonstration of the consequence of foiled terror plots. Sections of aircraft have also been supplied for film sets. | A television production company has blown up a plane to film a demonstration of the consequence of foiled terror plots.

| The Dutch Ministry of Defence has used facilities to test exactly how many explosives are needed to blow in the door on a 747, without injuring passengers. The SAS has used parts to work out how to gain access to aircraft by stealth, without blowing any holes but by using the existing structure of the plane. The police and armed forces have also come to shoot at seats to detect the behaviour of bullets in an aircraft environment. | The Dutch Ministry of Defence has used facilities to test exactly how many explosives are needed to blow in the door on a 747, without injuring passengers.

| Doors from an Indian Airlines A320 are currently in storage at Kemble and destined for a training company in Spain, to allow stewardesses to practise removing them and throwing them out to allow an emergency escape. The rear section of another Airbus is to be sliced off and sold to British Airways, to allow its baggage handlers to practise loading luggage into the hold. Its top half is being cut away and sent to a training college, possibly for fire drills. | Doors from an Indian Airlines A320 are currently in storage at Kemble and destined for a training company in Spain, to allow stewardesses to practise removing them and throwing them out to allow an emergency escape.

| One pilot even bought a complete flight deck of a veteran BAC 1-11 to installed in his home as a bar, proving there's plenty of uses for a plane long after it stops taking to the skies. | |
