Airbus's new A350 is built largely from lightweight composite materials, and has two ultra-quiet Rolls-Royce engines. The twin-aisle plane, also known as a wide-body, made its first flight just last week, ahead of the airshow.
It will compete with Boeing's 777 (which is older and heavier) as well as the 787 Dreamliner, which is also made from carbon-composite materials.

The A350 will come in three variants (the 800, 900 and 1000) and will carry between 250 and 350 people, more than its Boeing competitor. However, Boeing has just announced it will build a longer version of the 787, called the 787-10, which will carry up to 350 passengers. The first test flight of that aircraft is expected in 2017.
