You could call the F/A-18 Hornet a Mach 2 marathoner. In August 2005 the global fleet of the advanced fighter/attack aircraft broke the six million flight-hour mark, demonstrating its dependability and durability. U.S. planes clocked about 4.7 million of the six million flight hours. Other nations whose air forces fly the F/A-18 include Canada, Australia, Spain, Kuwait, Finland, Switzerland and Malaysia.
