Boeing 747

 The Boeing 747 entered service with Pan American Airlines in January 1970 and became the workhorse of the world’s long-haul, high-capacity fleet.

To-date, Boeing has delivered 1,365 747s in four basic types, the 747-100/-200/-300/-400. In November 2005, after many false starts, Boeing finally launched the 747-8 Intercontinental to serve the 400-500-seat markets and the Boeing 747-8 Freighter. 

The Boeing 747 was the first passenger jet to have a twin-aisle cabin section and a staircase leading to an upper deck in the nose section.
