Three members of Saudi Arabia’s Binladin family were killed in an air crash in the UK on 31 July. The names of the family members have not been released.

The private jet, which was travelling from Milan, crashed as it landed at Blackbushe airport in Hampshire, killing the pilot and all three passengers.

The aircraft is reported to have belonged to an aviation firm owned by the Binladin family, which also controls Saudi Arabia’s largest and most active construction company, Saudi Binladin Group (SBG).

Two other Binladin family members have died in aviation accidents. SBG founder Mohammed Binladin died in a plane crash in 1968 in Saudi Arabia, and his eldest son Salem Binladin died in a plane crash in Texas in 1988.

Founded in the 1930s, Jeddah-based SBG has enjoyed a leading market position in the Saudi construction sector for decades. According to regional projects tracker MEED Projects, it currently has nearly $33bn of work at the execution stage, which is almost the same as the $34bn of work held by the next nine busiest contractors in the kingdom combined.
