The Antonov An-225 Mriya is a strategic airlift cargo aircraft. It is powered by six turbofan engines and is the heaviest aircraft ever built, with a maximum takeoff weight of 640 tonnes.
It also has the largest wingspan of any aircraft in operational service.
On Jun. 24, 2021, the An-225 visited RAF Brize Norton coming from Karachi for a mission in support of NATO forces’ withdrawal from Afghanistan.
After dropping off its load (three RAF Puma helicopters) the Mriya departed again and its 6 turbofan engines broke the fence where several photographers and cameramen were taking shots and filming the take-off of the massive 6-engine aircraft.
The following video, posted to Youtube by Aviation Highlights shows the whole scene: pretty impressive.
