Qatar Airways unveiled its brand new Boeing 787 Dreamliner today at the Farnborough Airshow in the U.K. as the aircraft took to the skies for the first time in a flying display. The impressive demonstration of the plane's maneuverability was marked by steep climbs, tight banking and a "touch-and-go" landing, but perhaps the most striking feature of the 787 in flight (after an afternoon filled with the roar of jet fighters) was just how quiet it is.
