In September 2009, Boeing continued to make progress on the assembly of the 747-8 Freighter, as mechanics completed the installation of the new GEnx-2B engines on airplane No. 1 shown here in final assembly at the factory in Everett, Washington. With the GEnx-2B engines, the 747-8 Freighter will be 17 percent more fuel efficient than the 747-400 Freighter, resulting in a 17-percent reduction in carbon emissions. It also will have a noise footprint that is 30 percent smaller than its predecessor, making it a QC2-compliant airplane on both departure and arrival.
