Pictured: Osama bin Laden's Sister who Died alongside his Stepmother when their £7million Private Jet Exploded

Osama bin Laden's stepmother Rajaa Hashim, half-sister Sana bin Laden, and his brother-in-law, Zuhair Hashim, were all killed after a private jet owned by the family exploded into a fireball. They had overshot a runway while trying to land outside London.

Sana is pictured above sitting on a plane. She was killed alongside their Jordanian pilot, Mazen Al Doaja, when their £7million Embraer Phenom 300 jet overshot the runway at Blackbushe airport yesterday afternoon.

Sana was known amongst Saudis as 'Mother of Orphans', a sign of high esteem in Arab societies.

She was a renowned philanthropist with an active role in supporting orphanages and sponsoring orphans in Saudi. She was the sister of the renowned businessman Saad bin Laden.

Despite her wealth, she lived in a humble apartment and didn't have any house help. Her husband, Dr. Zuhair Hashim was an architect and a scientific researcher and writer.

The bin Laden-owned Embraer Phenom 300, pictured, had just arrived from Milan when it overshot the runway Osama Bin Laden, who claimed responsibility for the September 11 2001 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 sprawling construction conglomerate awarded many major building contracts in the Sunni kingdom. He died in a plane crash in Saudi Arabia in 1967.

Mohammed bin Awad bin Laden, Osama's father, is believed to have had around two dozen wives and a total of 54 children.

Saudi law allows for a maximum of four wives at any one time, though Mohammed bin Laden divorced frequently.

Rajaa Hashim was among those wives, making her Osama's stepmother, while daughter Sana would have been his half-sister, making Zuhair Hashim Osama's brother-in-law.

Mohammed bin Laden was originally from Yemen but moved to Saudi Arabia in the 1930s and became a building contractor for the SAudi Royal family.

Impressed with his work, they made his construction company the favoured contractor for many of the kingdom's building projects, which became more and more spectacular as the country was flooded with oil money.

He married Hamida Alia Ghanoum some time in the 1950s, and in 1957 she gave birth to Osama bin Laden, believed to be her only child.

While he grew up among the lavish trappings on wealth in the family's palatial home in Jeddah, he would go on to live a sparse life as the leader of hardline terror group Al Qaeda.

After masterminding several bomb plots around the world, including an attack on the World Trade Centre car park, he became the world's most wanted man in 2001 after terrorists from Al Qaeda crashed two planes into the towers, killing more than 5,000 people.

The Bin Laden family disowned Osama in 1994 when Saudi Arabia stripped him of his citizenship because of his militant activities. The al Qaida leader/terrorist was killed by US special forces in Pakistan in 2011.

Well wishers have taken to Twitter today to pay their respects to the departed four.
