At 9:31 AM Pacific Time at Boeing's Everett facility, the first 787 Dreamliner spooled up and started its twin Rolls-Royce Trent 1000 engines. The white smoke seen in the video is the engine storage oil being burnt off during the initial start.

At the time of the start, Liz Matzelle, who graciously provided the video, was standing at Everett's grassy knoll, about 2,200 feet from Stall 105 where ZA001 is parked. When asked about the sound of the engines starting up, Liz remarked that, "Lights are still on but I'm serious, there's no way to tell if the engines are running or not."
