The Curtiss R3C-2 Racer was the world's fastest airplane in 1925 when it captured the imagination and enthusiasm of the public for aviation.

At the start of the commercial jet age, at the end of the 1950s, cruise speeds were about 450 knots. The majority of turbofan-powered aircraft in today's world fleet have average cruise speeds of about 500 knots (Jane's, 1998).
The first commercial flight in 1914 hovered at a cruising altitude of just 5 feet in the air. In the 1930s, planes began to hit the 200 mph mark, and settled into a cruising altitude of about 13,000 feet.
According to Drela, today's airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds. (Cars also become more efficient at slower speeds on highways.)
First aircraft to exceed 160 km/h (100 mph) in level flight: Maurice Prévost flew a Deperdussin Monocoque in the 1913 Gordon Bennett Trophy race averaging over 160 km/h (100 mph) during a lap on September 28, 1913.
Absolute World Records are for a given distance or elapsed time, independent of Category, Group, or Class. The current holder of the Outright World Land Speed Record is ThrustSSC driven by Andy Green, a twin turbofan jet-powered car which achieved 763.035 mph - 1227.985 km/h - over one mile in October 1997.
Speed is often measured in kilometers per hour, but also in Mach, which corresponds to the speed of sound. For reference, Mach 1 is approximately 1,230 km/h. The Blackbird, an American military aircraft, holds the title of the fastest aircraft in the world with a top speed of Mach 3.32, or 3,540 km/h.
When an airplane experiences less drag, it consumes less fuel. This relationship between speed and fuel consumption means that flying at a slightly slower speed can result in significant fuel savings for airlines, which in turn can lower operating costs and potentially reduce ticket prices for passengers.
Flying Is Only Getting Safer Over TimeGlobal flight accident rates have been steadily declining over the years for a number of reasons, according to the International Civil Aviation Organization (ICAO).
