In aerobatics, the cobra maneuver (or just the cobra), also called dynamic deceleration, [1] among other names (see § Etymology), is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and making the plane into a full-body air brake ...
The Cobra, as performed by non-thrust vectoring aircraft, still depends on the aircraft moving through air; however, it does not involve the aircraft's aerodynamic surfaces and normal laminar airflow, but rather the whole airframe as a solid shape traveling through air, and its center of gravity in relation to the thrust vector.
The first ever record although not verified, was the 1903 Wright Flyer. It achieved 30 mph (48 km/h) during its first flight, a record by the only plane of controlled take-off and landing in existence. The Bleriot XI then reached 47 mph (76 km/h) in 1909. Fabric-covered biplanes of the World War I era and shortly after could reach 200 mph (320 ...

The Lockheed SR-71 Blackbird is the current record-holder for a crewed airbreathing jet aircraft. An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), [ 1 ] which also ratifies any claims.
This is a list of aircraft by date and usage.The date shown is the introduction of the first model of a line but not the current model. For instance, while "the most popular" aircraft, such as Boeing 737 and 747 were introduced in 1960x, their recent models were revealed in the 21st century.
The four-engine B-17 was developed by Boeing in the 1930s and dropped more bombs than any other American aircraft during World ... The Soviet Union received about two-thirds of the 3,303 planes ...
Famous versions used for racing included the twin aircraft known as "Cobra I" and "Cobra II," owned jointly by Bell Aircraft test pilots Tex Johnston and Jack Woolams. These aircraft were powered by an extensively modified 2000-horsepower engine, and a P-63 four-blade propeller. "Cobra I" with its pilot, Jack Woolams, was lost in 1946 during a ...
