Military spokesperson Ahmed Mohamed Ali on Tuesday posted on Facebook that the Air Force is conducting exercises until the end of the month, and urged citizens not to be disturbed by the sounds of planes in certain areas.
Explosions were heard in four Egyptian cities in October, which Ali said were from military aircraft breaking the sound barrier during training, denying allegations that Israeli planes had penetrated Egyptian airspace.
Egyptian presidential candidate Ahmed Shafiq's campaign boasted on Saturday that the former air force chief had shot down two Israeli planes during war, as it dismissed accusations of corruption.
Shafiq, former President Hosni Mubarak's last prime minister before an uprising toppled the dictator last year, claimed to have downed the planes during the War of Attrition which Egypt declared between 1969 and 1970.
"General Ahmed Shafiq has a great military record and career," his campaign statement said.
"Everyone recognized his achievements, starting with the downing of two Israeli planes during the War of Attrition, when the member of Parliament [who accused Shafiq of corruption] was maybe three years old," it said.
Lawmaker Essam Sultan had accused Shafiq of selling land at below market price to Mubarak's sons, who face trial with their father on corruption charges.
Mubarak also faces murder charges for the deaths of protesters during the revolt that ousted him on 11 February 2011.
Polls show Shafiq at third place in the 23 and 24 May 23 presidential election, which will begin a power transfer by Egypt's military rulers to the elected president.
Mubarak was seen as a close regional ally of Israel, but the main contenders in this month's election say they want to revise a 1979 peace treaty with the Jewish state, which remains unpopular in Egypt.
