THREE members of the bin Laden family were killed after their plane avoided a microlight and then landed too far down a runway, air accident investigators have found.

Relatives of al Qaida founder Osama bin Laden were among the four people, including the pilot, who died when the private jet crash-landed at a car auction site in Hampshire last week.

The Saudi-registered Phenom 300 jet, built in 2010, was trying to land at Blackbushe Airport when it crashed on to dozens of cars and burst into flames.

The Air Accidents Investigation Branch said the plane, travelling from Milan, overtook a microlight aircraft after starting its descent from cruise level.

It then landed two thirds of the way along the runway.

This gave it 438 metres to complete the landing when it needed 616 metres, investigators said.

After leaving the runway, the plane collided with a one-metre high earth bank causing part of the landing gear to detach and the plane to become briefly airborne.

It then collided with several parked cars 70 metres beyond the bank where the wings detached from the fuselage and the plane burst into flames.

Coroner for North Hampshire, Andrew Bradley, who opened and adjourned the inquest into the deaths, said the bodies were “incinerated”.

Mr Bradley confirmed the identities of the three members of bin Laden’s family as his stepmother Raja Bashir Hashem, 75, her daughter, Sana bin Laden, 53, and Zouheir Anuar Hashem, 56.

The Jordanian pilot was Mazen Salim Alqasim, 58, Mr Bradley said.

The Saudi ambassador to the UK offered his condolences to the bin Laden family, who own a major construction company in Saudi Arabia.

The statement said: “His Royal Highness Prince Mohammed bin Nawaf Al Saud … has paid his condolences to the family and relatives of Mohammed bin Laden at Blackbushe Airport in Britain for the great loss they have suffered as a result of the crash of the plane that was carrying the family.”

A further statement said the embassy would work with the British authorities to ensure a quick repatriation of the bodies for burial.

The plane had flown in from Malpensa Airport in Milan to the airfield.

Share article Bin Laden, who claimed responsibility for the 9/11 attacks in the United States, is believed to have had more than 50 brothers and sisters and many stepmothers.

His billionaire father Mohammed founded the Binladen Group, a construction conglomerate awarded major building contracts in Saudi Arabia. He died in a plane crash in 1967.
