Boeing 747 is in a class by itself.
From the first 747-100, during all 5 decades of operating, this type continues family legacy of the world's most advanced and efficient airplanes.
The 747 has completed more than 17 million flights through 2007. It has logged approximately 89 million flight hours or more than 10,000 years of flight time. The airplanes have flown approximately 42 billion nautical miles (78 billion kilometers), which is equivalent to making nearly 203,000 trips to the moon.
And that is not the end of the dinasty - the program builds out the remaining industry-leading 747-400ER Freighters and begins production of the new 747-8 family. Boeing will deliver the first 747-8 Freighter in late 2009 and the first 747-8 Intercontinental in late 2010.
Isnt it the real proof of leadership?
