This incredible footage shows a Boeing 787 Dreamliner create a giant cloud of vapour trail as it soars through the skies over Russia.

The amazing video, filmed from another plane, shows the contrail forming 33,000 feet in the air.

The passenger who shot the video wrote online: 'This contrail looks dark against the rising sun.'

Vapour trails occur when areas of low pressure form around the edge of the wing, creating vortices - tubes of circulating air - that leave trails behind the wing's tips.

The low pressure in these areas mean that cold air can condense, leaving spectacular trails of water or even ice behind the plane.


When a plane passes through a cloud, water vapour and ice from the clouds are sucked into the vortices, adding to the effect.

The air pressure created around the plane can also cut through a cloud, parting the vapours and leaving patterns behind as the clouds gather around the vortices.
