Did you miss it the first time around? This was one of the most-viewed stories on BT.com during 2015.
This is the stunning moment a Boeing 787 Dreamliner pilot performed a near vertical take-off.
The take-off and other impressive manoeuvres were displayed ahead of next week's opening of the 2015 Paris Air Show.
Test pilots pushed the 787-9, the newest version of the Dreamliner aircraft, into an extraordinarily steep climb, far steeper than any would be attempted on a commercial flight.
Footage of the Vietnam Airlines plane was filmed above Moses Lake in Washington and showcased some of the plane's many capabilities.
According to Boeing, the fuselage of the new plane is 20 feet longer than the 787-8, and can fly more passengers and more cargo further with the same environmental efficiency – using 20% less fuel use and emissions than the aeroplanes they replace.
