Atef (2005) observes that even before the terrorist attack of September 11, 2001, air security was among the government's main objectives. However, he goes on to explain that this program intensified after the September 11 terrorist attacks. Among the areas that have seen great improvement is improved flight training. An increase in flight school insurance premiums has had a number of negative impacts, including bankruptcy. This has therefore increased the need for the aviation industry to identify some ways to deal with the high cost of flying.
