3D model of a Korean Air Boeing 747-3B5 plane. The Boeing 747-3B5 is a variant of the iconic 747 series, specifically tailored for Korean Air. This wide-body commercial jet features four high-bypass turbofan engines, typically Pratt & Whitney JT9D-7R4G2 powerplants, each capable of producing up to 54,750 lbf (243.5 kN) of thrust. The aircraft has a maximum takeoff weight (MTOW) of approximately 833,000 lbs (377,842 kg) and can accommodate up to 400 passengers in a typical three-class configuration. With a cruising speed of about Mach 0.85 (907 km/h or 564 mph) and a range of around 7,400 nautical miles (13,700 km), the 747-3B5 was well-suited for Korean Air's long-haul international routes. The aircraft's distinctive hump-shaped upper deck houses the cockpit and additional seating, while its expansive main deck allows for flexible cabin layouts and cargo configurations.
