The Boeing 747-8 is a wide-body jet airliner developed by Boeing Commercial Airplanes. Officially announced in 2005, the 747-8 is the third generation of the 747, with a lengthened fuselage, redesigned wings, and improved efficiency. The 747-8 is the largest 747 version, the largest commercial aircraft built in the United States, and the longest passenger aircraft in the world.
Boeing Commercial Airplanes was established in two thousand four.
It's never mentioned when the company itself was established. It's difficult because the text mentions 2005 and I wrote out the year in words.
