Business class is almost replacing first class: 70% of 777s had first-class cabins before 2008 while 22% of new 777s and 787s had one in 2017.Full-flat seats in business-class rose from 65% of 777 deliveries in 2008 to nearly 100% of the 777s and 787s delivered in 2017, excepted for low-cost carriers having 10% premium cabin on their widebodies.
Advanced Supersonic Transport (AST) model in wind tunnel. The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft.
The aft end of the interior of NASA's Boeing 747 Shuttle Carrier Aircraft.The aft pressure bulkhead is the white circular component, and its web-like structure led a NASA technician with a sense of humor to add a large stuffed spider to the decor.

The Kline–Fogleman airfoil or KF airfoil is a simple airfoil design with single or multiple steps along the length of the wing. It was originally devised in the 1960s for paper airplanes. In the 21st century the KF airfoil has found renewed interest among hobbyist builders of radio-controlled aircraft, due to its simplicity of construction. [1]
The bubble canopy of a Lockheed Martin F-22 Raptor Canopy of an F-22 Raptor. An aircraft canopy is the transparent enclosure over the cockpit of some types of aircraft.An aircraft canopy provides a controlled and sometimes pressurized environment for the aircraft's occupants, and allows for a greater field of view over a traditional flight deck.
The parts are sent to the main plant of the plane company, where the production line is located. In the case of large planes, production lines dedicated to the assembly of certain parts of the plane can exist, especially the wings and the fuselage. [54] [55] When complete, a plane is rigorously inspected to search for imperfections and defects.
Some older types of aircraft design utilized open truss structure constructed of wood, steel, or aluminum tubing. [1]: 3–3 This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood.
