King Khalid asked the US President Jimmy Carter to sell advanced fighter planes to Saudi Arabia to assist in countering communist aggression in the area. The delivery of the first of sixty F-15s under the agreement approved by Carter arrived in the Kingdom in 1982. He purchased a Boeing 747 with an operating room should he be stricken while on his travels. Jimmy Carter in his memoirs stated that both King Khalid and then Crown Prince Fahd assured him of "their unequivocal support for Sadat", but they would realize no concrete move in this direction, at least not publicly.
