The Airbus A380 has hit an airport hangar in Bangkok, forcing the world's largest passenger jet to delay its takeoff today on a demonstration tour.

The bump caused slight damage to the left wing of the double-decker plane, an Airbus official said.

The A380 arrived in Bangkok yesterday on the first leg of its four-city Asian tour, and was to make a round trip from Bangkok to Thailand's northern tourist hub, Chiang Mai, early today.

The bump forced the plane to delay its departure for several hours, the official said, adding that the accident happened because of miscommunication between pilots and ground staff.
