Such technology solves problem of longer, thinner, energy-saving wings not fitting in airports around the world

Airbus has said it will test folding wings for the next generation of its bestselling planes, as the world’s largest planemaker races to work out the shape of future commercial aircraft by the end of the decade.

Longer, thinner wings made of light but strong composite materials offer the promise of energy savings but present a problem for manufacturers because they will not fit in airports around the world, many of which are already at or near full capacity.
