Khashoggi headed a company called Triad International Holding Company which among other things built the Triad Center in Salt Lake City, which later went bankrupt.[15] He was famed as an arms dealer, brokering deals between US firms and the Saudi government, most actively in the 1960s and 1970s. In the documentary series The Mayfair Set, Saudi author Said Aburish states that one of Khashoggi’s first deals was providing David Stirling with weapons for a covert mission in Yemen during the Aden Emergency in 1963.
