About Aircraft

The Boeing 747 is an American wide-body commercial jet airliner and cargo aircraft, often referred to by its original nickname, Jumbo Jet. Its distinctive "hump" upper deck along the forward part of the aircraft makes it among the world's most recognizable aircraft,[6] and it was the first wide-body produced. Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 was envisioned to have 150 percent greater capacity than the Boeing 707,[7] one of the common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 years.[8] As of January 2017, the 747 has been involved in 60 hull losses, resulting in 3722 fatalities.

 

The Boeing 747-400 is an improvement of the 747-300, and is the best-selling model of the Boeing 747 family of jet airliners. While retaining the four-engine wide-body layout of its predecessors, the 747-400 embodies numerous technological and structural changes to produce a more efficient airframe. Its most distinguishing features versus preceding 747 models are 6-foot (1.8 m) winglets mounted on 6-foot (1.8 m) wing tip extensions, which are found on all 747-400s except for Japanese domestic market versions.
