Aluminium has been the standard material used in aircraft for more than a century - even the Wright brothers' famous first flight in 1903 used an aircraft made partially from the metal. But the 'aluminium age' could be about to end - with the delivery of the first large-scale commercial aircraft made using 50 per cent 'composite materials' including plastics and carbon fibre.
The much-delayed Boeing Dreamliner 787 can fly 10,000 miles, is far quieter than ordinary jets, and is constructed using a 'moulding' process that has eliminated 1,500 aluminum sheets and 50,000 fasteners. It's also three years late - and has cost a reported $32 billion.
Scott Fancher, vice president and general manager of the 787 programme, said: 'It took a lot of hard work to get to this day.'
The first Boeing 787s - delivered to All Nippon
Airways - are 20 per cent more fuel-efficient than rivals, but also
offer in-flight luxuries such as electrically dimmed windows
All Nippon Airways is the first airline to take
delivery of the hi-tech new plane - the first large-scale commercial
jetliner to be built from composite materials, not aluminium
The hi-tech new aircraft seats 250-290 and
offers increased comfort - the air inside is less dry than comparable
jets, and First Class passengers will enjoy entertainment on 17-inch
touchscreens
It offers hi-tech entertainment with Android touchscreens built into every seat - even in Economy. The 'composite' design - using mixed materials such as titanium and carbon fibre - is believed to have been a spur for rival Airbus to incorporate carbon fibre in future aircraft.

the 787 Dreamliner - with fuselage assembled from composite sections
rather than huge numbers of aluminium sheets
Boeing has taken orders for 821 Dreamliners, which will compete with the future Airbus A350, due in 2013.
One of the components that gives the 787
Dreamliner its extraordinary range and fuel economy - 20 per cent less
than other equivalent aircraft - are its engines, hi-tech new models
made by Rolls Royce.
'You can tell the Dreamliner is special the moment you see it coming in to land,' says Jonathan Margolis, a technology specialist who saw one of its first test flights, 'The near silence is almost spooky. But the thing which struck me most when I saw it at the Farnborough Air Show was the obvious suppleness of the composite structure. You can clearly see the wings flexing. It almost looks like an Airfix kit.'
'Speaking to the pilot later, he confirmed that as a result of its ultra-light airframe, the 787 is exceptionally manoeuvrable and easy to fly precisely.'

The plane's lighter weight allows airlines to operate routes even when the demand is insufficient for larger aircraft like the Boeing 777 or 747, or the Airbus 380 superjumbo.
Fancher added: 'For aviation we believe this is as important as the 707 was with the introduction of the jet age.
He moved to head off any fears over the new materials, stressing the tough moulded composites used to create the aircraft were nothing like ordinary plastic.
'Plastic is what you have on the dashboard of your car. This is not plastic,' he told reporters.
The 787 development program has been delayed seven times due to challenges with engineering, supply chain glitches and a 58-day labor strike in 2008.
'We have been waiting for the 787 for over 3 years as we expected it in the summer of 2008,' said senior vice president Satoru Fujiki who took part in negotiations to buy the 787.
The techniques used to create the 787 Dreamliner
have eliminated the need for multiple aluminium sheets and up to 50,000
fasteners
ANA has ordered a total of 55 Dreamliners worth $11billion at current list prices, including 40 of the 260-passenger 787-8 variant being delivered this week.
Some of the aircraft's 20 per cent fuel
efficiency gains are thanks to extensive wind-tunnel testing at
facilities including Britain's Farnborough air base
The Seattle Times reported on Sunday that 787 program costs had topped $32 billion due to delays. That estimate raised questions, the newspaper said, over whether the new jet would make money for Boeing before 'well into the 2020s, if ever.' Boeing declined comment on the claims.
Analysts say new jets typically cost closer to $15billion.
Analysts have speculated that the huge delays in
delivering the hi-tech new jet could mean Boeing will not turn a profit
until 2020

efficient Boeing model
Also uncertain is how many planes Boeing must sell to break even, something the company is not yet saying.
'If it is 1,200, they should make money; if it is larger than that it could be challenging,' Hamilton said.
The delivery comes as Boeing remains locked in a dispute with one of its top labor unions in Washington state, where it has traditionally built its aircraft.
The International Association of Machinists and the National Labor Relations Board accuse Boeing of building a non-union 787 plant in South Carolina to punish the IAM for past strikes.
Boeing denies that claim, saying the jobs in South Carolina represent new employment, not the relocation of existing work.
