Boeing 747-100 marks milestone in aviation history as only one remains active

The Boeing 747-100, the first model of the iconic jumbo jet, revolutionized commercial aviation by significantly lowering travel costs and increasing capacity. Over 1,500 units were produced across various models, with the 747-100 being the original variant. Pan Am played a crucial role in the 747's development, ordering 25 aircraft in 1966, which influenced its design. The aircraft featured a unique raised cockpit and a nose door, allowing for efficient loading. Today, only one 747-100 remains active, serving as a tanker for the Iran Air Force. The first 747-100, known as the City of Everett, is on display at the Museum of Flight in Seattle, where visitors can explore its history.
