The largest commercial aircraft ever built, it has undoubtedly been a significant milestone in aviation. With 251 aircraft ordered, the A380 has been far from a failure, but changing markets and improvements in twin-engine aircraft have made other aircraft more appealing. This guide takes an in-depth look at this incredible aircraft, from its origins to the possible future for it. It will also look at the aircraft design, configurations ... The A380 was the third Airbus aircraft to fly on 100% sustainable aviation fuel in a 12-month period. An A350 was the first in March 2021, followed by an A319neo in October 2021. The A380 is a truly unique aircraft in more ways than one, and will continue to fly our skies for years to come.
