1969 Aswan Ilyushin Il-18 crash 1969 Aswan Ilyushin Il-18 crash On 20 March 1969, a United Arab Airlines Ilyushin Il-18 crashed while attempting to land at Aswan Airport. 100 of the 105 passengers and crew on board were killed in the crash. The flight was a non-scheduled international passenger service from Jeddah, Saudi Arabia to Aswan, Egypt. The aircraft was carrying home Muslim worshippers who had won a pilgrimage through a lottery. It was dark in the early morning when the flight attempted to land and blowing sand had reduced visibility to 2–3 kilometers. After two unsuccessful attempts to land, the aircraft was making a
Aswan Dam year. The annual crop consumptive use of water is about . Hence, the overall irrigation efficiency is 38/46 = 0.82 or 82%. This is a relatively-high irrigation efficiency. The field irrigation efficiencies are much less, but the losses are reused downstream. This continuous reuse accounts for the high overall efficiency. The following table shows that the equal distribution of irrigation water over the branch canals taking off from the one main irrigation canal, the Mansuriya Canal near Giza, leaves much to be desired: The salt concentration of the water in the Aswan reservoir is about , a very low salinity
