On December 15, 2009, Boeing's 787 Dreamliner took its
first flight, achieving a major milestone in the plane's eventual commercial deployment. Now, as it moves towards that goal, the 787 has been put through a series of new tests, most recently its stall test, in which the pilots take it high in the sky and intentionally cut power to its engines to ensure that they can recover in flight.
Here, one of the first 787s is seen flying high over the snow-capped mountains of the Pacific Northwest.
