A private jet which crashed, killing three members of Osama bin Laden's family, landed too far down the runway because it was travelling 40% faster than the recommended speed, accident investigators concluded.

The Saudi-registered Phenom 300 jet smashed into an earth bank at the end of the runway at Blackbushe Airport, Surrey, on July 31 last year before becoming airborne and colliding with several parked cars.

The occupants survived the impacts but died from the effects of a fire which began after the wing separated from the fuselage, the Air Accidents Investigation Branch (AAIB) said.
