This is the Antonov An-225, the world's heaviest aircraft, landing at a maximum overload of around 1,320,000 lbs. It dented the runway.
This shot was taken by Stephen McParlin at Fanborough, England in 1990. If you're wondering just how big this plane is, here's one next to a 747, making the Boeing look like a toy glider.
