Abu Ayyub was one of the Ansar (Arabic: الأنصار, meaning aiders, helpers or patrons) of the early Islamic history, those who supported Muhammad after the hijra (migration) to Medina in 622.

The Allison T61 (known internally as the Allison 550-B1) was a 6,500-shaft-horsepower (4,800-kilowatt) turboprop engine that was to power the 1959 version of the proposed Lockheed Super Hercules military and civil freight aircraft. The U.S. Air Force (USAF) had helped Allison fund the development of the T61 for four years. Lockheed had received orders from Pan American World Airways and Slick Airways for a total of 18 aircraft, but both orders were contingent on the military ordering the aircraft by September 30, 1959, around the date that the USAF's engine development contract expired. The development contract was extended temporarily to November 30, 1959, but the T61 development effort was canceled by January 1960, after USD$37.5 million had been put into the engine's development. Four T61 engines had run on the test stand at the time of cancellation. The Allison T61 produced 6,500 equivalent shp (4,800 kW) at takeoff, of which 6,102 shp (4,550 kW) came from the propeller, with 995 pounds (451 kg) of residual jet thrust. It had a similar appearance to the Allison T56 but with a split compressor section instead of a single stage. The T61 improved on the power-to-weight ratio of the T56 by 30%.

Khalid bin Abdulaziz Al Saud (Arabic: خالد بن عبد العزيز آل سعود‎ Khalid ibn ‘Abd al ‘Azīz Āl Su‘ūd; 13 February 1913 – 13 June 1982) was King of Saudi Arabia from 25 March 1975 to his death. Khalid was one of the sons of King Abdulaziz, the founder of modern Saudi Arabia. He served as viceroy of the Hejaz region for a brief time in the 1930s. Khalid represented Saudi Arabia abroad as a diplomat. He visited the United States in 1943, establishing relations between the two countries. Khalid was appointed as the deputy prime minister of Saudi Arabia in 1962, and his brother King Faisal named him as crown prince in 1965. Following the murder of King Faisal, Khalid ascended to the throne. His reign saw both huge developments in the country due to increase in oil revenues and significant events in the Middle East. In 1979, a group of civilians seized the Grand Mosque of Mecca and sought but failed to kidnap Khalid. Saudi forces regained control over the mosque, but the seizure resulted in the introduction of stricter religious policies in Saudi Arabia. King Khalid died in 1982 and was succeeded by his brother Fahd.
