To make it simple i found this of google (still no video!)

G-VSKY was badly damaged when it made a partial wheels-up landing at London Heathrow on November 6th 1997. The crew reported problems with the landing gear and after a low pass over the airport the Tower confirmed that the right main gear was not extended. During the following emergency landing, the other main gear collapsed and the aircraft skidded on its engines and fuselage along the runway emitting sparks. All 100 passengers evacuated unharmed whereas the A340 was so severly damaged that the repair work took over 2 months. The investigation showed that a bolt of the right main gear was broken and jammed the gear
