First Dreamliner flight from British airline Yesterday, United Airlines diverted one of its Dreamliners bound for Houston from Heathrow, to New Jersey, because of a low oil indication, making it the second 787 flight in three days to be cut short due to an oil-related problem. On Tuesday, a United 787 on its way to Tokyo from Denver was diverted after an indication of a problem with an oil filter in an engine. The Dreamliner should have entered passenger service in 2008 but it was not until October 2011 that the first commercial flight was operated by Japanese carrier All Nippon Airways. When a Qatar Airlines flew its Dreamliner's maiden long-haul flight into Heathrow in December last year, Peter Hughes was on board. He said the high ceiling, subtle lighting and windows 30 per cent larger than on a 767, made the plane "feel positively cavernous." The Dreamliner has been described as the world's most environmentally-friendly aeroplane - it uses 20 per cent less fuel, costs 30 per cent less to maintain and produces 60 per cent less noise pollution than any other aircraft of the same size. The aircraft is also the first to abandon the "bleed air" system which scientists claim causes aerotoxic syndrome - an illness that can result in dizziness, nausea and breathing difficulties.
