Boeing 747-400
Boeing 747-400 is considered one of the most preferred aircraft in the Boeing 747 family worldwide with a seating capacity of 524 in typical two-class configuration and 416 in a three-class configuration. In 1966, when Boeing first announced the creation of a 747 Jumbo Jet, aviation experts criticised the technical specifications and predicted that it would be impossible to fly an aircraft of 'that' size. Over 50,000 employees worked relentlessly in the initial development phase of the 747 family.
