ABOVE: US Army Apaches log five million flight hours

Boeing recently reached a unique milestone when the US Army’s AH-64 Apache attack helicopters officially reached five million flight hours. The accomplishment is equivalent to flying nonstop for more than 208,333 days, or 570 years and nine months.

Additionally, 1.3 million of those five million flight hours were accomplished during combat. The AH-64 first flew in 1984, and since then the US Army has operated A, D and E-model Apaches. It currently operates D and E models, along with nineteen other countries.
