Boeing's new "lean and green" Dreamliner aircraft, due to be delivered to a number of UK airlines, has suffered another delay, it was announced today.
US-based Boeing said the delivery of the first Boeing 787 Dreamliner - to Japan's All Nippon Airways - had been put back from the end of this year to around February 2011.
The Dreamliner, whose UK customers include British Airways, Virgin Atlantic and Thomson Airways, is already more than two years behind schedule.
Boeing said the latest delay was due to the availability of a Rolls-Royce engine needed for the final phases of flight testing.
Boeing said it was working with Rolls-Royce to "expedite engine availability".
The Dreamliner has been hailed as a revolutionary plane, emitting less carbon dioxide than other aircraft.
Boeing, which has had to contend with numerous production difficulties with the 787, displayed the Dreamliner at the Farnborough Air Show in Hampshire earlier this summer.
