H-4 Hercules ("Spruce Goose"). Due to its ungainly form—exacerbated in that the first airplane remained unpainted for some time, due to the need for immediate testing—Boeing Commercial Airplanes president Scott Carson jokingly apologized to 747 designer Joe Sutter that he was "sorry for what we did to your plane." Operational history Flight testing On September 16, 2006, N747BC arrived at Boeing Field, Seattle to complete the flight test program. Swing-tail testing was done at the Boeing factory in Everett. The second airplane, N780BA, made its inaugural test flight on February 16, 2007. The third began modification in 2007. The first two LCFs entered service in 2007 to support the final assembly of the first 787s. Delivery times for the 787's wings, built in Japan, was reduced from around 30 days to just over eight hours with the Dreamlifter. Evergreen International Airlines (unrelated to EVA Air or EGAT), a U.S. air freight operator based in McMinnville, Oregon, operated the LCF fleet until August 2010. Then Atlas Air, which was awarded a nine-year contract for the operation of the aircraft in March 2010, took over LCF operation. Evergreen had achieved a 93% on flight schedule performance with the LCF, and sued Boeing for $175 million, which the court mostly dismissed. Into service In December 2006, Boeing announced the 747 LCF would be named Dreamlifter, a reference to the 787's name, Dreamliner. It unveiled a standard livery for the aircraft that included a logo reminiscent of the 787's Dreamliner logo. Certification was initially planned for early 2007, but was pushed back to June 2007. The aircraft's winglets were removed to resolve excess vibration and other handling characteristics prior to final certification. In the meantime, as part of the flight test program, LCF delivered major sections of the 787 from partner sites around the world to the Boeing factory in Everett, Washington for final assembly. The 747 LCF was granted FAA type certification on June 2, 2007. From its first flight in 2006 until certification in 2007, the Dreamlifter completed 437 hours of flight testing along with 639 hours of ground testing. Of the four 747 Dreamlifters Boeing acquired, three were complete and operational by June 2008, and the fourth became operational in February 2010. On July 1, 2020, a Dreamlifter arrived at Salt Lake City International Airport, carrying 500,000 face masks to be used by Utah school children and teachers as part of
