The Boeing 747 raises more emotions than maybe any other airliner and is therefore affectionately known as "Jumbo". Its successor the 747-8, which offers innovation, advanced technology and efficiency, made its first flight on 20 March 2011. As a completely new aircraft development the Boeing 747-8 builds on the positive qualities of the proven Boeing 747 series. The 747-8 is 5.6 meters longer than the previous Boeing 747-400 and has a maximum take-off weight of 442tons. The wings have significantly improved aerodynamics and newly designed wingtips.
