In 1972, Mubarak became Commander of the Air Force and Egyptian Deputy Minister of Defense. On 6 October 1973, at the breakout of the Yom Kippur War, the Egyptian Air Force launched a surprise attack on Israeli soldiers on the east bank of the Suez Canal. Egyptian pilots hit 90% of their targets, making Mubarak a national hero. The next year he was promoted to Air Chief Marshal in recognition of service during the October War of 1973 against Israel. Mubarak was credited in some publications for Egypt's initial strong performance in the war. The Egyptian analyst Mohamed Hassanein Heikal said the Air Force played a mostly psychological role in the war, providing an inspirational sight for the Egyptian ground troops who carried out the crossing of the Suez Canal, rather than for any military necessity. However Mubarak's influence was also disputed by Shahdan El-Shazli, the daughter of the former Egyptian military Chief of Staff Saad el-Shazly. She said Mubarak exaggerated his role in the 1973 war. In an interview with the Egyptian independent newspaper Almasry Alyoum (26 February 2011), El-Shazli said Mubarak altered documents to take credit from her father for the initial success of the Egyptian forces in 1973. She also said photographs pertaining to the discussions in the military command room were altered and Saad El-Shazli was erased and replaced with Mubarak. She stated she intended to take legal action.
