A pilot has captured stunning footage of the contrails of a Boeing 787 Dreamliner over eastern Russia.
Contrails are line-shaped clouds produced by aircraft engine exhaust, typically at aircraft cruise altitudes several miles above the Earth’s surface.
They are composed primarily of water, in the form of ice crystals.
Lou Boyer was piloting a Boeing 747 flight from Tokyo to Alaska when he saw the contrails over eastern Russia.
The Dreamliner was flying towards Asia when Boyer spotted it passing 1000ft below his own aircraft. The pilot described the event as “normal traffic separation on an airway.”
“Due to volcanic activity in the area, quite a few flights were on the same route over eastern Russia,” Boyer told.
“The combination of high relative humidity and a nice sunrise gave this contrail a nice deep color as the contrail created its own shadow,” he added.
