What is the high speed of 747?

Boeing 747-400 – 1056km/h (656mph) The venerable 747-400 makes it on this list despite being in service for over 35 years. It is the most common variant of the 747, and its mix of long-range and high speed made this a very popular plane with airlines in its heyday.



The Boeing 747, famously known as the "Queen of the Skies," is one of the fastest commercial jetliners ever built. Its typical cruising speed is Mach 0.85 to 0.855 (about 560–570 mph or 910–920 km/h), but it has a maximum operating speed (Mmo​) of Mach 0.92. This makes it significantly faster than its modern twin-engine counterparts like the Boeing 787 or Airbus A350, which usually cruise closer to Mach 0.82. In certain conditions, particularly when catching a strong tailwind from the jet stream, the 747 has been known to reach ground speeds exceeding 800 mph (though its airspeed remains subsonic). The 747-8, the final and most advanced version, features a redesigned wing and more powerful engines that allow it to maintain these high speeds with greater efficiency. This "speed advantage" can shave up to 30–45 minutes off a long-haul trans-Atlantic or trans-Pacific flight compared to slower aircraft. Despite its retirement from many passenger fleets, the 747's high-speed capability remains legendary among pilots and aviation enthusiasts.

The fastest fighter jet ever created was the NASA/USAF X-15. It was an experimental aircraft that resembled more of a rocket with wings but managed to reach a record 4,520mph. The fastest fighter jet in the world today is the MiG-25 Foxbat, with a top speed of 2,190mph, half the speed of the X-15.

Mach 10 speed has never been achieved by a manned aircraft, though, so it has never been tested. Mach 10 has, however, been achieved by a spacecraft - on November 16, 2004, NASA launched the X-43A, an air-breathing hypersonic vehicle, and was able to reach real Mach 10 while being pushed into the atmosphere.

About Concorde With a take-off speed of 220 knots (250mph) and a cruising speed of 1350mph – more than twice the speed of sound - a typical London to New York crossing would take a little less than three and a half hours, as opposed to about eight hours for a subsonic flight.

Supercharged: Concorde was the first -- and still only -- passenger aircraft that had turbojet engines with afterburners. Raw fuel was introduced into the exhaust of the plane's four engines, immediately increasing the engines' thrust by almost 20%.

Let's start with a look at the most famous of jets, the Boeing 747. The Boeing website states that this model, with a gas tank capacity of 63,500 gallons, may burn five gallons of jet fuel per mile of flight.

The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.

Such speed didn't come cheap, though: A transatlantic flight required the high-maintenance aircraft to gulp jet fuel at the rate of one ton per seat, and the average round-trip price was $12,000.

So, to answer the question, yes, some fighter jets are faster than the Concorde. However, it is important to note that the Concorde was primarily designed for passenger travel, not for combat or aerial maneuvers.

Concorde is sadly no longer flying, but it is still possible to visit some of the remaining 18 airframes, there are others not open to the public but you can still see them.

Boom Supersonic, the US plane manufacturer, plans to have the answer with its new Overture jet, which is set to transport customers at twice the speed of today's fastest commercial aircraft, and is regarded as the new Concorde.

Maverick breaks the Mach 10 speed barrier in the movie, a speed that is practically impossible for a human to achieve due to extreme G-forces and potential damage to the body. The real-life SR-72, which the Darkstar prototype is based on, is under development but won't come close to the Mach 10 speed seen in the film.

MORE DETAILS

The speed at which you break the sound barrier depends on many conditions, including weather and altitude. It's approximately 770 mph or 1,239 kmh at sea level.
